- WHAT'S GOING ON AROUND US
- AAG ANNUAL MEETING Paper Sessions of Interest to GSG Members
GEOMORPHORUM is issued twice per year. Current and past issues are archived at http://www.cla.sc.edu/geog/gsgdocs through the generous efforts of Allan James. If you forget the URL above, the web page is easily accessed by getting on the AAG web page (http://www.aag.org/), clicking on 'Specialty Groups,' and scrolling down to 'Geomorphology.'
The purpose of GEOMORPHORUM is to serve members of the Geomorphology Specialty Group (GSG), Association of American Geographers, by providing a forum for the exchange of ideas and news about geomorphology and related matters, and to foster improved communication within our community of scholars and affiliated professionals.
Individuals are encouraged to forward submissions to the Editor in so far as they improve understanding of the internal workings of our community, contribute to the health of geomorphology, adhere to standards of professional conduct, foster the spirit of collegial interaction, and satisfy the overall goals of the newsletter. News of new initiatives, recent appointments, promotions, research grants, and awards are acceptable, whereas advertisements for new faculty positions or graduate student opportunities at specific institutions are generally not (these are handled via other media, including Geomorphlist and the AAG Newsletter). Recent graduates (both Masters and Ph.D.) are invited to provide their name, thesis title, date examined, five descriptive key words, a list of related publications, and a contact address. Those attending or planning field meetings, conferences, or workshops are also encouraged to submit short reports. The Editor reserves the right to edit submissions as appropriate.

It was just over half a century ago (at an AAG annual meeting) that A.N. Strahler first publicly articulated his ideas on the quantitative treatment of process and form. Geomorphologists readily embraced the new paradigm. However, the essential point--that Strahler’s dynamic approach to the study of landforms was predicated on an appreciation of both statistical analysis and mathematical methods--has taken time to register. The recent, practically motivated shift in the emphasis of geomorphological enquiry has placed substantial weight on the acquisition and synthesis of data for the purpose of prediction and control. Causal explanations are not sufficiently utilitarian to fulfill the need for general accounts of landform development that both facilitate understanding and have predictive power, which is instead being met by mathematical models.
Controversy surrounding the role of mathematics in the Earth Sciences is not new. For example, the earliest applications of mathematical analysis to geological phenomenon presented a compelling challenge to Lyell’s (1830-33) uniformitarian perspective on land surface sculpture. Principal commentators, such as William Hopkins, preferred the ‘naked dignity of demonstrative truth’ to ‘vague and misty sublimity’ (Hopkins, 1836, 365-6). In utilizing mathematical methods to provide accurate and uniform proofs of the effects of natural phenomena, they sought to advance geology and elevate it to a rank among the physical sciences (Smith, 1985). Strahler (1950, p. 209) was similarly motivated. Echoes of the argument that geological actions can be reduced to mathematical and geometrical laws, thus rendering them part of a global phenomenon rather than a local anomaly, also permeate the contemporary debate about scientific realism in geomorphology.
My concern is that geomorphologists in Geography departments throughout the USA are in danger of becoming disengaged from many of the fundamental intellectual issues with which they have traditionally been concerned because they lack mathematical skills. The problem will be exacerbated if mathematics continues to be excluded from the curriculum; acceptance of the new culture of calculation is a precursor to alleviating it. Thus, I contend that all geomorphologists should necessarily have an appreciation of basic mathematical methods. I also suggest that mathematics should be viewed in the same light as tools, such as remote sensing and geographic information systems, that are now generally applied throughout Physical Geography, and also afford us the opportunity to obtain new insights into the operation of biophysical systems at a variety of temporal and spatial scales.
Note that I take issue with the representation of scientific knowledge, rather than with the character of theory and its development. Thus my advocacy of a more mathematical approach should not be misconstrued as an infatuation with the rouged lips of fashion. It arises from a basic proposition articulated by C.E. Thorn:
"Geographers with a mathematical training are at a distinct advantage over those who do not have one. This primarily stems from the access such training gives them to the main body of scientific literature, and the opportunity it offers to conduct their own research in a similar, or at least compatible fashion. However, the majority of geomorphologists still lack an adequate mathematical background. The net result is a divergence; in an already small community, two groups are developing using different languages. The mathematical group is able to understand the nonmathematical one, but the inverse is not true." (Thorn, 1988, p. 194)
A critical implication of Thorn’s thesis is that if we fail to modify our perspective of the physical processes that sustain and transform the earth’s surface we will become increasingly less able to comprehend the significant contributions that are made within geomorphology. A potentially deleterious consequence is that our students will appear to be inadequately trained by comparison with their peers who emerge, for example, from Geology departments, who they will inevitably encounter in the job market.
Mathematics incorporates a system of symbols and abstract terms that are unambiguous and expressly defined by their function in the context of the range of experience to which they apply. A fundamental requirement is, therefore, that the significance of these symbolic statements is understood. There is nothing sacrosanct about symbology (the system of notation adopted is typically determined by convention). Solving (translating) any equation at all simply requires that we are privy to the meaning of the constituent parameters. Similar acquired skills are required in the humanities. For example, the subject-verb-object sentence structure of English is not a universal condition, thus the accurate translation of German into English requires the knowledge that the latter is a subject-object-verb language. The ability to understand any mathematics is then predicated on the expectation that one is cognizant of the meaning of the symbols used to represent particular quantities (which will remain esoteric gibberish until formally defined, communicated, and understood). Some knowledge of the tools of mathematical description and analysis is required.
Mathematical concepts and techniques are taught in order of increasing complexity, since in order to comprehend differential and integral calculus, a knowledge of functions and algebra is required (cf. Berlinski, 1998). Some basic expressions, such as the equation for a straight line, or precepts such as applying a function to a number have been widely used in geomorphology. The dissemination of more advanced mathematical knowledge, such as a fundamental understanding of partial differential equations, may lie beyond our pedagogical objectives. However, a basic understanding of many simpler concepts is necessarily required to comprehend statements that are outlined in numerical form. This includes the ability to manipulate simple expressions. Dimensional analysis, which builds on the intuitive notion that physically correct equations should be dimensionally balanced (homogeneous), is a case in point (Strahler, 1958). The property of dimensional homogeneity not only permits the consistency of an equation to be tested, it also imposes conditions on the quantities involved in a physical problem and provides evidence of the form of the relation connecting their magnitudes (cf. Shields, 1936). In the case of geomorphological applications, it also has the additional appeal of keeping spatial scale from complicating an analysis (cf. Church and Mark, 1980).
Geographers quite naturally subscribe to a range of views about the relevance of scientific method and of the utility of quantitative techniques and particular brands of theory. Though conscious of their historical imperatives and of the need to accentuate their concern with the physical environment with an appreciation of human activities, most geomorphologists subscribe to the view that their discipline is a field of natural science. No novel theoretical developments are required for geomorphologists in departments of Geography (or Geology) to continue to engage in productive research, but any individual’s ability to advance understanding of (or communicate information about) the physical world may be constrained by their appreciation of mathematical methods. Indeed, a cursory perusal of the specialist journals forces one to conclude that some mathematical knowledge is now required to comprehend the literature of the discipline. From this perspective alone it seems desirable that all geomorphologists should be familiar with the symbology of mathematics and with the common mathematical functions, as well as with the principles involved in manipulating simple expressions on which simple and subtle concepts such as dimensional analysis rely.
I emphasize that it is not my intent to imply that the study of landforms should be replaced with a tour of the calculus. In Geography departments, however, I perceive that the post-modern assault on objectivity is in danger of depriving geomorphologists of a fundamental tool. It would be an irrevocable pedagogical mistake for us not to resist the imposition of a dumbed-down culture in which even the simplest mathematics is viewed esoteric gibberish. Failure to do so will inevitably weaken our position with respect to cognate disciplines that encourage mathematical rigor, and may also serve to make our work less relevant to contemporary society.
Geomorphologists in Geography departments were remarkably prescient in their advocacy of statistical methods. It may prove more difficult for us to accept the new ‘culture of calculation’, and its elaboration may not be universally required or desirable since geomorphology, like all science, operates on a variety of levels. Nevertheless, to sustain an eclectic approach to the study of landforms, we need to ensure that indifference to mathematics does not inhibit understanding or translate into ignorance.

These materials and other supporting documentation should be sent before February 1.
A few years back, someone had the idea that the GSG should make T-shirts with the GSG logo available to its members. The primary motivation for doing this would be to raise much-needed funds for the GSG rather than improve the sartorial elegance of geomorphologists. Well, theory and practice often fail to consummate their relationship, and the idea appears to have been passed along the GSG hierarchy until it landed in the lap of the current Secretary-Treasurer. Some of you noticed an announcement to this effect in the last Geomorphorum and another across the Geomorphlist, and a handful of you even expressed interest in purchasing said T-shirts. Unfortunately, a handful of purchases does not a financial dynasty make. Apologies to those who placed orders and are expecting delivery of GSG T-shirts in New York. Perhaps we can re-visit this issue at the GSG Business Meeting.
The good news is that the Preliminary Program for the AAG Annual Meeting in New York (Feb 28 – March 3) is chock-full of interesting stuff for geomorphologists. The bad news is that there is so much stuff going on, that it will be impossible to attend everything. In order to help you with your planning, we have extracted all those paper sessions that might be of interest to geomorphologists, and have appended them to the bottom of this newsletter. Note that these were taken from the Preliminary Program, and some sessions are subject to change. Please check the Final Program when it becomes available on the AAG web page (http://www.aag.org/).
Please make every effort to support your colleagues presenting in paper sessions scheduled early in the morning, late in the afternoon, and on the last day of the conference.***** OF SPECIAL NOTE *****

1) GEOMORPHOLOGY COMES TO KENTUCKY
The University of Kentucky Department of Geography has initiated a physical geography program specializing in geomorphology. Long recognized as a highly-ranked human geography program, the U.K. geography department in1999 made a strategic decision to build a physical program of comparable quality, and in 2000 began implementing the program, with a focus on geomorphology and surficial processes.
The first university field camps in the U.S. in both geography and geology were in Kentucky. Physiography was the first geography course taught at the University of Kentucky. And, Kentucky landforms and landscapes such as Mammoth Cave and the sinkhole plain and the extraordinarily dissected Appalachians of eastern Kentucky have been instrumental in the development of several branches of geomorphology. Thus it was perhaps inevitable that the UK geography department would add a physical geography program focusing on geomorphology.While the department has always taught undergraduate physical geography courses, a physical geography research and graduate program is a new development. Jonathan Phillips came to Kentucky from Texas A&M in August, 2000 to begin the effort, and will be joined by Alice Turkington from Queen's University-Belfast in August 2001.A search for a third physical geography faculty position will take place in 2001. Phillips specializes in fluvial and soil geomorphology, pedology, and nonlinear dynamical systems applications in geosciences. Turkington's interests include weathering processes and urban geomorphology. Both have interests in broad issues of multiple causality, convergence, and divergence in landform and landscape evolution. The Department recently completed construction of a new physical geography laboratory, and is in the midst of pursuing possible development of interdisciplinary initiatives in surficial processes and GIS/remote sensing. For more information, visit the web site at http://www.uky.edu/AS/Geography/dept/physical.htm.
2) GEOMORPHOLOGY EVOLVES AT MICHIGAN STATE
Lake Quaternary landscape evolution is a growing focus in the Geography Department at Michigan State University, where Randy Schaetzl and Alan Arbogast are developing what they hope will be one of the leading centers of field-based research in the great Lakes region. Geomorphologic research and teaching at MSU emphasizes the interactions between landforms, soils, and environmental change. Soils-based research is done within a geomorphological framework, while geomorphic research often utilizes soils and paleosols as indicators of landform age or the chronology of landscape evolution. Paleoenvironmental reconstruction is a significant component of our research, with the primary goal to determine the range of (paleo) environmental conditions within a region and how they affect landscapes. Within geomorphology, our program emphasizes a wide range of processes including soils, glacial, coastal, fluvial, and eolian. Glacial geomorphology focuses on the northern Great Lakes region, and often employs soils or surficial sediments to interpret the various glacial depositional environments, or to better understand the development/evolution of these landforms over time. We also have a focus on mapping of glacial landforms. Coastal geomorphology is centered on the shore of Lake Michigan and is associated with high resolution monitoring of shorezone processes and change using GPS and remote sensing. Work in fluvial geomorphology focuses on the investigation of the post-glacial history of watersheds and streams in Michigan by reconstructing the evolution of alluvial fills, terraces, and changes in stream characteristics.
A goal in this fluvial study is to integrate the influence of Holocene climate change into an understanding of river systems in Michigan, and to examine post-settlement adjustments. Eolian landscapes currently being studied include both coastal and inland dunes within Michigan, and dune fields on the Great Plains. In both areas, the aim is to determine the chronology of dune evolution and the variables that promote activation and/or stabilization of dunes. Thus, buried soils are frequently used as chronostratigraphic markers through radiocarbon dating. We are also developing an interest in dating eolian and outwash sands using optimally-stimulated luminescence. Within soils, the research emphasis is on soil genesis within a variety of geomorphologic contexts. Soil chronosequence and chronofunction work has been a strong part of the Department in the past. Work on pedoturbation and soil evolution continues to be a research topic of ongoing interest. Since soils are important keys to (paleo) sedimentologic environments, identification of these environments, through the use of soil maps and other spatial date, are important components of our work. For example, we are currently using soils data to identify areas of eolian activity in Michigan, to understand some of the many aspects of glaciogenic depositional processes, and to decipher the glacial lake chronology, based on soils formed in probable glaciolacustrine sediments. Finally, we are very interested in the links between soils and vegetation in the upper Midwest. To learn more, see http://www.geo.msu.edu/soils.html.
3) GEOGRAPHY OF THE WEST FIELD CAMP
Oregon's Basin & Range and Cascade Volcanic provinces are miles and environments apart. The Basin & Range fault blocks lie in the semiarid cattle country of sparsely populated southeastern Oregon. Conversely, the high Cascade volcanoes tower over the humid, coniferous forest-cloaked Cascade Range and are within an hour's drive of much of Oregon's population. These distinct regions have in common public lands, wilderness designation, and rugged topography shaped by volcanism and extreme weather and climate.
The field camp involves exploration and research components. Students explore the biophysical, human, and resource geography east of the Cascade crest through field observation, discussion, presentations, and readings. Ultimately, students conduct intensive research at Steens Mountain in the Basin & Range and at Mount Hood in the northern Oregon Cascades. In the new Steens Mountain Wilderness, students: 1) inventory, map and assess the biophysical condition of backcountry campsites; and 2) create a geomorphic map. At the Mount Hood Wilderness, students survey and map the current, historic and Little Ice Age glacier termini. Through intensive research, students enhance critical thinking, field observation, topographic map analysis, airphoto interpretation, data collection, mapping, writing, and presentation skills.
When: 16 July-19 August 2001; Logistics: 1) travel in CWU vans; 2) van travel and backpack to Steens Mountain sites; 3) backpack to Mount Hood Wilderness sites; and 4) share in cooking & clean-up duties. Students may stay on-campus while in Ellensburg. Cost: $1550 U.S. (est.) includes undergraduate tuition & fees, field food, camping, and transportation. Add ~$380 for CWU graduate credit.
Info/Application: Contact Professor Lillquist via US mail, e-mail, or the department web page for more information. To apply, submit: 1) brief application letter explaining why you wish to participate; 2) photocopy of college transcripts; and 3) faculty letter of recommendation. All application materials should be received by 1 May 2001 but later applications will be considered on a space available basis.

A new text, An Annotated Guide to the Artwork of the United States Boundary Commission, by Jerry E. Mueller (jmuel98132@aol.com), documents the artwork prepared during the years 1850-1853 under the direction of John Russell Bartlett, and describes some 250 images in pencil, sepia and wash, and watercolor. These drawings were prepared largely by Bartlett himself, although there are significant contributions from Henry Brown, Oscar Bessau, Harrison Eastman, Seth Eastman, and Henry Pratt. The images cover a wide variety of subjects on both sides of the US-Mexican border. Approximately 120 of the drawings have been reproduced in black and white on a series of 42 pages at the end of the book. Included in the introduction to the text is a discussion of the most important research findings related to the origin and attributes of the drawings. Also included are tables of all the woodcuts and lithographs found in Bartlett’s Personal Narrative of Exploration and Incidents in Texas, New Mexico, California, Sonora, and Chihuahua, connected with The United States and Mexican Boundary Commission, during the years 1850, ’51, ’52, and ’53, published in two volumes in 1854. Each figure in Personal Narrative is cross-listed in the tables to the corresponding drawing and artist of record presented in the Annotated Guide.
Why is this book of relevance to GSG members?
1. The artwork of 1850-1853 predates the era of reliable photography in the Southwest, and therefore represents (in most cases), the earliest graphic record of the borderland region. Included in the artwork are many landscape scenes: Texas Hill Country, Guadalupe Peak, Organ Mountains, Mimbres Mountains, Peloncillos, Chiricahuas, Sutter Buttes, etc., plus rivers and valleys such as the Pecos, Salt, Gila, and Colorado.
2. The text discusses the attributes of each drawing, and where known, inferences with respect to environmental change. For example, Bartlett sketched and described the character (including geometry) of the Pecos River at Horsehead Crossing in 1850, to which I have added a brief description of the river's character today. There are several drawings from in and around the Yuma area that depict quite dramatically the confluence of the Colorado and Gila Rivers in 1852, a junction that today is much further north. Bartlett produced a sepia and wash of Napa Valley, also in 1852. I found his vantage point on Glass Mountain, but soon discovered that the scene today is obscured by both haze and a greater prevalence of woody vegetation, especially trees. The same situation applies to the New Almaden Quicksilver mining area that Bartlett sketched.
3. The text describes certain scenes recorded by Bartlett that are basically intact in the modern landscape. Others, such as several scenes of the Santa Rita Copper Mines, have been destroyed or obliterated by mining, and still others have been lost to urbanization. Bartlett's drawings of Casas Grandes in 1852 can be compared to the modern condition of the ruins to assess the rate of decay of the structure in the last 150 years.
4. The collection of drawings is a great source of illustrations for publications in the earth sciences. The New Mexico Bureau of Mines and the New Mexico Geological Society have both featured Bartlett scenes in their publications. The book incorporates Bartlett's brief geologic descriptions and interpretations. I find it interesting that he would call most rocks with visible quartz sandstone, even where he was dealing with granite, although he wasn't necessarily consistent on this matter. He has a great description of the geomorphic development of the terraces developed in limestone south of Fredericksburg Texas.

1) REFLECTIONS ON THE COMMITTEE ON GEOGRAPHY by Will Graf
The Committee on Geography (CoG) is the only disciplinary-defined committee in the National Research Council, the action arm of the National Academy of Sciences. The purpose of CoG is to provide input to the academies and to the federal government on all things geographic, including geomorphology. Because the committee reports to the Board on Earth Sciences and Resources, it directly interacts with typical earth science specialists ranging from geophysicists to economic geologists. There is considerable interest in geomorphology and geography in the academies and the federal government for two reasons. First, geomorphology is widely recognized as the interface science between the solid earth and the atmosphere, so that major issues such as global climate change have strong connections to the earth science community through geomorphology. Second, the earth science community seems to be struggling with the issue of making better connections to society and culture, and there is widespread opinion that geography may offer a conduit to the social sciences. Considerable work is still needed, both to educate the earth science community what geomorphology and geography have to offer, and to educate the geomorphologic and geographic communities about opportunities to meld science and policy. Hopefully, GSG members will rise to the occasion. Contact any member of the CoG and share your thoughts and ideas (http://www4.nationalacademies.org/cger/besr.nsf/ and click on 'Standing Committees').
2) NSF's EARTH SYSTEM HISTORY PROGRAM by James Knox
INTRODUCTION - Earth System History (ESH) is a research initiative of the U.S. Global Change Research Program (USGCRP). It includes coordinated paleoscience programs supported by NSF Divisions of Atmospheric Sciences (ATM), Earth Sciences (EAR) and Ocean Sciences (OCE), as well as the Office of Polar Programs (OPP) and NOAA Office of Global Programs. As the paleoscience component of the US Global Change Research Program (USGCRP), the emphasis of ESH is upon Earth's climate system. In this context, the term "Earth system" refers to the atmosphere and those components of the ocean, cryosphere, hydrosphere, and terrestrial systems that contribute or respond to climate conditions. ESH proposals need not focus purely upon climate per se, but it should be clear how the project will contribute to understanding climate related processes and system response.
The goal of ESH research is to understand the natural variability of the Earth system through records preserved in geo-biologic archives and to contribute to a comprehensive understanding of climate change with annual to millennial resolution, including the forcing mechanisms, interactions and feedbacks among its components.
AREAS OF SPECIAL EMPHASIS - The ESH Program invites proposals in the following areas of special emphasis.
- Paleoclimate Variability at Annual-Decadal Resolution: Proposals should address the collection and analysis of high-resolution time series to advance the study of patterns, processes, and causes of interannual to decade-scale climatic and environmental variability. Priorities within this area of emphasis are to define the full range of natural environmental and climatic variability, to understand how this variability is affected by changes in external forcing, and to focus on societally-relevant climate variability.
- Rapid Climate Change: Proposals should address the use of paleoclimate records to document the frequency, temporal resolution, and spatial extent of past rapid climate changes, particularly those that have occurred during interglacial warm periods such as the Holocene. The use of paleoclimate data in combination with modern climate dynamics, meteorology, and climate modeling is highly encouraged
- Extreme Warm Conditions: Proposals should address such issues as (a) improved characterization of intervals with climates warmer than those of the present, (b) conceptual models to explain the origin and/or termination of warm states, and (c) the feedbacks that maintain global climate during a warm phase.
- Spatial Patterns of Climate Change. Proposals should address large-scale spatial aspects of climate change, particularly tropical-extratropical linkages and interhemispheric comparisons revealed in continuous marine and terrestrial records. Understanding spatial patterns of past climate changes, the degree of synchroneity or phasing between different areas, and the relation between low latitude and high latitude regions are critical aspects of paleoclimate studies and are necessary to test and improve climate models.
- Arctic Paleoclimate Studies. The sensitivity of the Arctic to climate change and the fundamental importance of the cryosphere as an influence on the climate system mandate special attention to Arctic paleoclimate research.
- Modeling of Past Change: Proposals should focus on the use of Earth system models to investigate the patterns, processes, and causes of past climatic and environmental change.
For all areas of emphasis, priority will be given to proposals that seek to use the record of past conditions to understand the dynamics of climate/Earth system processes or to integrate local/regional responses into the large-scale climate system.
ADDITIONAL INFORMATION - ESH is described more fully in National Science Program Announcement NSF 00-11 available at: http://www.nsf.gov/cgi-bin/getpub?nsf0011. ESH Program Managers are: David Verardo (dverardo@nsf.gov) and Richard Poore (rpoore@nsf.gov).The Deadline for proposal receipt is normally February 14th.
