Depth to soft bedrock - 20 to 40 inches. Platy, granular, subangular blocky or is massive. These are the Devoy , Rooset , Spinlin , Tatiyee and Wilpar series. Devoy soils have A and B horizons and a lithic contact at 20 to 40 inches. Rooset, Tatiyee and Wilpar soils lack bedrock at depth of 40 inches or less.
Spinlin soils have secondary carbonates in their profiles.
Home Camp soils are on mountain and plateau side slopes. Slopes are 4 to 50 percent. Elevations are 6,000 to 7,400 feet. These soils formed in residuum and colluvium weathered from tuff, andesite, and basalt with minor admixtures from volcanic ash. The climate is cold continental having a mean annual precipitation of 12 to 16 inches.
