Desert Research Institute Division of Earth & Ecosystem Sciences (DEES) DTF Highlight: Catalog of Analogs: Terrain Similarities between the U.S. Army Yuma Proving Ground and Central Southwest Asia Catalog of Analogs employs the predictive methodology developed for the DTF program to identify similarities desert materiél development and testing by identifying the best U.S. landscape analogs for international conflict areas. Initial comparisons were conducted at Yuma Proving Ground, Yuma, Arizona. Future work will expand this initiative to other U.S. military training and testing areas. 114°30'0"W 114°20'0"W 114°10'0"W 114°0'0"W 113°50'0"W 113°40'0"W 33°30'0"N Generalized Surface Soil [with USCS Symbol] - Typical Landform not mapped silty clay to clayey silt; silty sand [CL-ML; SM] - badlands poorly graded sand [SP] - sand seas/dunes poorly graded sand with silt and gravel [SP-SM (>15% gravel)] - alluvial plains poorly graded gravel with silt and sand [GP-GM] - alluvial fans silty gravel with sand [GM] - mountain highlands, pediments 32°50'0"N 32°50'0"N 33°0'0"N 33°0'0"N 33°10'0"N 33°10'0"N 33°20'0"N 33°20'0"N 33°30'0"N 32°40'0"N 0 5 10 Miles 0 5 10 Kilometers 32°40'0"N 114°30'0"W 114°20'0"W 114°10'0"W 114°0'0"W 113°50'0"W 113°40'0"W GM 28.5% CL-ML; SM 1.4% SP 0.2% SP-SM 8.4% Generalized Surface Material Characteristics of YPG Soil [USCS Symbol] Landform(s) Area Area Area (mi 2 ) (km 2 ) (%) CL-ML; SM SP SP-SM GP-GM GM Badlands Sand seas/dunes Alluvial plains Alluvial fans Mountain highlands, pediments 18.3 2.5 110.2 805.1 373.1 47.4 6.4 285.5 2,085.2 966.3 1.4 0.2 8.4 61.5 28.5 GP-GM 61.5% SURFACE SOILS IN YPG (total area = ~1,300 sq mi (~3,400 sq km))
