Layers with consistence that is hard, firm and brittle are in most pedons. Stratified sandy loam to silty clay loam. May have a small amount of mica. There are no competing series. Gardnerville and Geysen series are similar.
Gardnerville soils have a fine montmorillonitic particle-size control section.
Bloor soils are on fan skirts, lake plain, axial stream flood plains and alluvial flats. These soils formed in alluvium from mixed rock with a component of loess. Slopes are 0 to 8 percent. Elevations are 4,000 to 5,800 feet. The climate is cool, semiarid with warm, dry summers and cool, moist winters.
