A Spatial Representation of Louis Peltier's Weathering, Erosion, and Climatic Graphs Using Geographic Information Systems Track: Mining and Geosciences Author(s): Rell Fowler, James Petersen This study is based on Louis C. Peltier's 1950 study "The Geographic Cycle in Periglacial Regions as it is Related to Climatic Geomorphology" published in the Association of American Geographers (AAG) and uses graphs that define the Chemical Weathering, Frost Action, Weathering Regions, Pluvial Erosion, Mass Movement, Wind Action and Morphogenetic Regions based on Mean Annual Temperature and Mean Annual Precipitation. The goal of this study is to create maps of the continental United States for each of Peltier's graphs. The data for this project is from the United States Department of Agriculture's (USDA) Natural Resources Conservation Service (NRCS) and is in PRISM data for the time period 1961-1990. The ASCII raster text format covers the lower forty-eight States. The raster files are processed using a complex methodology that employs GIS, Excel, Word, TextPad and WordPad to derive the new raster images. The resulting maps are used to illustrate the weathering, erosion and climatic processes occurring within the continental United States per Peltier's graphs. Rell Fowler HDR Engineering, Inc.
