Chama soil series
The Chama series consists of well drained soils formed in materials weathered from soft siltstone, mudstone and shale on uplands. These soils are moderately deep to soft siltstone, mudstone or shale. These soils are moderately or moderately slowly permeable. Slope ranges from 0 to 45 percent. Mean annual air temperature is 42 degrees F, and mean annual precipitation is 15 inches.
TAXONOMIC CLASS: Fine-silty, mixed, superactive, frigid Typic Calciustolls
Depth to soft bedrock ranges from 20 to 40 inches. The mollic epipedon ranges from 7 to 10 inches thick.
USE AND VEGETATION: Soils are cropped to small grains, which are mostly wheat; a significant acreage is in rangeland. The native vegetation is principally western wheatgrass, needleandthread and blue grama.
DISTRIBUTION AND EXTENT: Western North Dakota, eastern Montana, and possibly northwestern South Dakota. The series is of large extent.
