Haverly soils are in alpine meadow areas and have slopes of 0 to 30 percent. Haverly loam, grassland. Thickness of the umbric epipedon ranges from 7 to 15 inches, thickness of solum ranges from 15 to 30 inches, and depth to bedrock ranges from 20 to 40 inches. Organic carbon in the umbric epipdon ranges from 1 to 6 percent and decreases uniformly with increasing depth. Rock fragments range from 5 to 35 percent and are mostly stones.
Structure is granular or crumb and consistence is soft or slightly hard.
Reaction is very strongly acid or strongly acid and the horizon is less than 50 percent base saturated. The horizon usually has common distinct to prominent mottles. Texture is typically stony sandy loam, but the fine earth fraction ranges in clay from 5 to 18 percent and sand is over 52 percent. Reaction ranges from extremely to strongly acid. These are the Ptarmigan and Strain series.
