These include the Rifle series, which is the only other series in that family and the closely related Greenwood , Lupton , and Spalding series. Rifle and Greenwood soils have hemic material with mostly herbaceous fiber. Also Greenwood soils are more acid. Lupton soils have sapric material dominant in the subsurface tier. Spalding soils are more acid.
Mooselake soils are in bogs within lake plains, outwash plains, and glacial moraines.
They have slopes of less than 1 percent. They formed primarily in moderately decomposed woody material that is more than 51 inches thick. Glacial sediments of variable texture underlie this material commonly beginning at depths of 5 to 10 feet. The main ones are the more acid Greenwood soils, which occur primarily in less sloping portions of bogs than the Mooselake soils. Associated mineral soils primarily include those developed in reddish, noncalcareous loamy glacial till such as the Ahmeek and Duluth soils and their respective topographic associates.
