The soils formed in glacial till derived mainly from slate, shale, and phyllite with small amounts of granite, fine grained quartzite, and sandstone. The mean annual air temperature ranges from 41 to 46 degrees F, and the mean annual precipitation ranges from 34 to 46 inches. The frost-free season ranges from 100 to 150 days. Elevation ranges from 10 to 1000 feet above mean sea level. These are the Bangor , Burnham , Monarda , and Thorndike soils.
Bangor soils are well drained, and are in higher positions on the landscape.
Burnham soils are very poorly drained, and are in the lowest positions on the landscape. Monarda soils are poorly drained, and are in lower positions on the landscape. Thorndike soils are somewhat excessively drained, have bedrock within 20 inches of the surface, and are in higher positions on the landscape. Moderately well and somewhat poorly drained. Permeability is moderate in the A and upper part of the B horizons, and moderately slow or slow in the lower B and C horizons.
