There are no competing series in the same family. Brownsto , Crago , and Luhon series are in the same subgroup and have bedrock deeper than 20 inches. The Conpeak soils are on hillslopes, ridges, and dissected pediments that have plane or convex surfaces. The slope gradient is commonly 5 to 20 percent but ranges from 2 to 45 percent. The soils formed in residuum and colluvial slopewash derived dominantly from sandstone and siltstone.
Rock outcrops are common.
Elevation is 7,000 to 8,500 feet. The mean annual precipitation is 10 to 14 inches with the majority falling as snow in November through May 15, but these areas are windswept and only that precipitation falling in April and May enters the soil. Estimated frost-free season is 40 to 80 days. These soils are used for grazing. Native vegetation is Indian ricegrass, needleandthread, Sandberg bluegrass, threadleaf sedge, and mat muhly.
