Cover Photo: Landsat Thematic Mapper imagery (30 m) and digital orthophoto quad- rangles were fused together to produce this high-resolution image of the Beartooth Mountains on the Custer National Forest near Red Lodge, Montana. Rock Creek drainage is in the center and Red Lodge Ski Area to the right. This perspective view was generated by draping the merged imagery over a digital elevation model (10 m). 1 Soil and Water Program Manager, Bridger-Teton National Forest, Jackson, WY. 2 Natural Resource Information System (NRIS) Terra Program Coordinator, Intermountain Region, Ogden, UT. 3 Ecologist, NRIS Terra Staff, Washington Office, Sandy, OR. 4 Ecologist, Pacific Northwest Region, Portland, OR. 5 Ecologist, Eastern Region, Milwaukee, WI. 6 Ecologist, Intermountain Region, Ogden, UT. 7 Soil Scientist, NRIS Terra Staff, Washington Office, Sandy, OR. 8 Supervisory Soil Scientist, Southwest Region, Phoenix, AZ. 9 Assistant Province Geologist, Sierra National Forest, Pacific Southwest Region, Clovis, CA. 10 Geologist, NRIS Terra Staff, Washington Office, Sandy, OR. 11 Ecologist, North Central Research Station, Rhinelander, WI. 12 Regional Soil Scientist, Southwest Region, Albuquerque, NM.

It provides a set of national standards, suggested method- ologies, and a list of criteria for defining, describing, and classifying terrestrial ecological units and types. The TEUI Technical Guide provides the standard for development of terrestrial ecological units at the landtype association, landtype, and landtype phase levels of the National Hierarchy Framework of Ecological Units (Cleland et al. 1997). The TEUI Technical Guide is not intended to replace the correlation process of the National Cooperative Soil Survey (NCSS). It relies on the NCSS process to ensure quality control of all TEUI products, particularly soils data. The following references may be useful in development of the TEUI and supplement the direction contained in this technical guide: • Draft Forest Service Manual 1940, Resource Inventories and Monitoring and Ecosystem Assessments (in press). • Draft Forest Service Handbook 1909.xx, Resource Inventories and Monitoring and Ecosystem Assessments (in press). • National Soil Survey Handbook (USDA NRCS 2003b). • Soil Survey Manual (USDA NRCS Revised 1993). • Keys to Soil Taxonomy (USDA NRCS 2003a). • National Forestry Handbook (USDA NRCS 2004). • National Forestry Manual (USDA NRCS 2000). • Field Book for Describing and Sampling Soils, Ver. 2.0 (Schoeneberger et al. 2002).

In memory of Tagish ABSTRACT Recently documented ice patch sites in the southwest Yukon are ideal for evaluating precontact hunter-gatherer land-use patterns in the western subarctic. Located in the alpine of the mountainous regions of the boreal forest, ice patches are associated with well preserved hunting equipment, caribou (Rangifer tarandus) dung and an abundance of faunal remains dating to over 8000 years ago. However, current models are inadequate for explaining caribou hunting at ice patches as they tend to emphasize large-scale communal hunts associated with latitudinal movements of caribou. Much less is known about the alititudinal movment of caribou and the associated hunting forays to ice patches in the alpine.

  • Place Names: an Analysis of Published Materials
    DOCUMENT RESUME ED 319 675 SO 020 925 AUTHOR Anderson, Paul S. TITLE Seeking a Core of Wo' -'d Regional Geography Place Names: An Analysis of Published Materials. PUB DATE 14 Oct 89 NOTE 18p.; Paper presentel at the Annual Meeting of the National Council for Geographic Education (Hershey, PA, October 11-14, 1989). Updated April 1990. PUB TYPE Speeches/Conference Papers (150) -- Reference Materials - Geographic Materials (133) -- Information Analyses (070) EDRS PRICE MF01/PC01 Plus Postage. DESCRIPTORS Elementary Secondary Education; *Geographic Location; *Geography Instruction; *Minimum Competencies; *Physical Geography IDENTIFIERS Place Names ABSTRACT Knowing place names is not the essence of geography, but some knowledge of names of geographical locations is widely considered to be basic information. Whether used in general cultural literacy, lighthearted Trivial Pursuit, educational sixth grade social studies, or serious debates on world events, place names and their locations are assumed to be known. At the college level of world regional geography courses, five books with lists of place names are in print by geographers: Fuson; MacKinnon; Pontius and Woodward; DiLisio; and Stoltman. Those five sources plus place name lists by P.S. Anderson and from Hirsch reveal similarities and diversities in their content. A core list of place names is presented with several cross-classifications by region, type of geographic feature, and grade level of students. The results reveal a logical progression of complexity that could assist geography educators to increase student learning and avoid duplication of efforts. There will never be complete agreement about any listing of the core geographical place names, but the presented lists are intended to stimulate discussion along constructive avenues.

  • Cold-Climate Landform Patterns in the Sudetes. Effects of Lithology, Relief and Glacial History
    ACTA UNIVERSITATIS CAROLINAE 2000 GEOGRAPHICA, XXXV, SUPPLEMENTUM, PAG. 185–210 Cold-climate landform patterns in the Sudetes. Effects of lithology, relief and glacial history ANDRZEJ TRACZYK, PIOTR MIGOŃ University of Wrocław, Department of Geography, Wrocław, Poland ABSTRACT The Sudetes have the whole range of landforms and deposits, traditionally described as periglacial. These include blockfields and blockslopes, frost-riven cliffs, tors and cryoplanation terraces, solifluction mantles, rock glaciers, talus slopes and patterned ground and loess covers. This paper examines the influence, which lithology and structure, inherited relief and time may have had on their development. It appears that different rock types support different associations of cold climate landforms. Rock glaciers, blockfields and blockstreams develop on massive, well-jointed rocks. Cryogenic terraces, rock steps, patterned ground and heterogenic solifluction mantles are typical for most metamorphic rocks. No distinctive landforms occur on rocks breaking down through microgelivation. The variety of slope form is largely inherited from pre- Pleistocene times and includes convex-concave, stepped, pediment-like, gravitational rectilinear and concave free face-talus slopes. In spite of ubiquitous solifluction and permafrost creep no uniform characteristic ‘periglacial’ slope profile has been created. Mid-Pleistocene trimline has been identified on nunataks in the formerly glaciated part of the Sudetes and in their foreland. Hence it is proposed that rock-cut periglacial relief of the Sudetes is the cumulative effect of many successive cold periods during the Pleistocene and the last glacial period alone was of relatively minor importance. By contrast, slope cover deposits are usually of the Last Glacial age. Key words: cold-climate landforms, the Sudetes 1.
