Vasquez soils are in concave positions or depressions such as drain heads, shallow basins, and cirque basins above timber line, or in seepage areas on steep slopes. Slope gradients range from 0 to 30 percent. These soils formed in locally transported strongly acid glacial till, alluvium, or valley fill materials derived principally from gneiss and schist bedrock. A fluctuating water table occur in these soils at most seasons. These are the Naverly, Nystrom, and Ptarmigan soils.
Naverly soils lack an aquic moisture regime.
Nystrom soils are Nistisols. Ptarmigan soils lack an aquic moisture regime. These soils have a fluctuating high water table. These soils are used as native pastureland, and for recreational purposes. They have considerable importance for wildlife, and they are very influential in controlling the late summer stream flow from the mountainous areas.
