Slopes range from 3 to 60 percent. Mean annual temperature ranges from 40 to 45 degrees F, mean annual precipitation ranges from 35 to 55 inches, and mean frost-free days ranges from 90 to 145 days. Elevation ranges from 500 to 2000 feet above sea level. They moderately well drained Crary soils form a drainage sequence with Potsdam soils and occupy footslopes and other less convex areas. The competing Becket and Marlow soils are in nearby areas that lack a nearly stone-free surficial mantle.
Worth soils occur in areas that have a fragipan.
Tunbridge soils are associated where bedrock is at a depth of 20 to 40 inches. Other geographically associated soils are the Adams , Berkshire , and Colton soils. Adams and Colton soils are in glaciofluvial sand and gravel deposits. The competing Berkshire soils are on associated till plains, but lack a dense substratum. Runoff is medium to rapid.
