In addition all of these soils, except Waiska are in areas receiving more than 32 inches of mean annual precipitation. Guardlake soils are in nearly level to gently rolling slopes of outwash areas, kames, and eskers. Slope gradients range from 0 to 35 percent. Mean annual temperature ranges from 41 to 43 degrees F. Mean annual precipitation ranges from 28 to 32 inches. These are the Emmet , Kalkaska , and Posen soils on similar landscape positions and the Solona soils.
Emmet soils are coarse-loamy and have fewer rock fragments.
Kalkaska soils are very deep, sandy soils. Posen soils are loamy- skeletal and have more rock fragments. The somewhat poorly drained Solona soils are in lower landscape positions. Surface runoff is slow to rapid. Permeability is moderate in the loamy part and very rapid in the substratum.
