The Killarney series consists of very deep, moderately well drained soils with fragipans on foot slopes in mountainous areas. They formed in slope alluvium mixed with loess and the underlying slope alluvium or residuum derived from rhyolite or granite rocks.
Permeability is moderate above the fragipan and very slow in the fragipan.
Slopes range from 8 to 50 percent. Mean annual temperature is 56 degrees F, and mean annual precipitation is 42 inches. Killarney very cobbly silt loam, very stony - on a 17 percent northeast slope with mixed hardwood and shortleaf pine at 1,050 feet elevation. 37 degrees 30 minutes 6 seconds N. and long. This is the Airmont series.
