The Highsplint series consists of deep and very deep, well drained soils on mountains and hills.
Permeability is moderate or moderately rapid.
These soils formed in stony, loamy colluvium from sandstone, siltstone, and shale sedimentary rocks. Slopes range from 5 to 100 percent, but are dominantly 35 to 75 percent. Thickness of the solum ranges from 40 to 60 inches or more. Depth to bedrock ranges from 48 to 60 inches or more. Rock fragments, mostly channers and flagstones, commonly make up 35 to 90 percent of the soil.
