Myersville soils have a solum 20 to 40 inches thick that is dominated by greenstone. Neshaminy soils have moderate slow permeability and the solum is dominated by subrounded diabase and angular quartz pebbles. Penn soils have low shrink-swell potential and the solum ranges from 18 to 36 inches thick. Ryder soils have low shrink-swell potential and the solum ranges from 20 to 36 inches thick. Washington soils have moderate permeability and have quartz, gneiss and chert rock fragments.
Wheeling soils have moderate permeability and low shrink-swell potential.
Hayter soils are gently sloping to moderately steep. Slopes range from 0 to 35 percent. These soils are on colluvial fans or benches and smooth or convex sideslopes. They formed in a regolith weathered from sandstone, shale, and minor amounts of limestone which has rolled or washed down from the higher slopes. The mean annual precipitation ranges from about 43 to 50 inches.
