TAXONOMIC CLASS: Sandy, mixed, thermic Typic Haplocambids The mean annual precipitation is about 5 inches and the mean annual temperature is about 59 degrees F. Eclipse soils are on stream terraces and lacustrine terraces and have slopes of 0 to 5 percent. The Eclipse series consists of very deep, somewhat excessively drained soils formed in alluvium from mixed rock sources. Official Series Description - ECLIPSE Series
