The Palisade 1:24,000 quadrangle is in Mesa County in westernColorado. Because the map area is dominated by various surficialdeposits, the map depicts 22 different Quaternary units. Twoprominent river terraces are present in the quadrangle containinggravels deposited by the Colorado River. The map area containsmany mass movement deposits. Extensive landslide deposits arepresent along the eastern part of the quadrangle. These massivelandslides originate on the flanks of Grand Mesa, in the GreenRiver and Wasatch Formations, and flow west onto the Palisadequadrangle. In addition, large areas of the eastern and southernparts of the map are covered by extensive pediment surfaces.These pediment surfaces are underlain by debris flow depositsalso originating from Grand Mesa. Material in these depositsconsists of mainly subangular basalt cobbles and boulders andindicate that these debris flow deposits have traveled as much as10 km from their source area. The pediment surfaces have beendivided into 5 age classes based on their height abovesurrounding drainages.Two common bedrock units in the map area are the Mancos Shale andthe Mesaverde Group both of Upper Cretaceous age. The Mancosshale is common in low lying areas near the western map border.The Mesaverde Group forms prominent sandstone cliffs in thenorth-central map area.The map is accompanied by a separate pamphlet containing unitdescriptions, a section on geologic hazards (includinglandslides, piping, gullying, expansive soils, and flooding), anda section on economic geology (including sand and gravel, andcoal). A table indicates what map units are susceptible to agiven hazard. Approximately twenty references are cited at theend of the report.
