These are the Antler , Gilby , Moritz and Tetonview series. Antler soils have less than 15 percent fine sand and coarser in the upper horizons. Gilby soils have less than 18 percent clay in the upper horizons. Moritz soils do not have rock fragments in the particle-size control section and formed in alluvium. Tetonview soils have O horizons and occur at elevations above 3800 feet.
Hamerly soils are on level and nearly level till plains.
They are also on flats and slight rises on till plains and lake plains, and on slightly convex slopes surrounding shallow depressions on till plains. Slopes are short and commonly having gradients of less than 3 percent but range from 0 to 3 percent. The soil is formed in calcareous loamy till. Mean annual air temperature ranges from 36 to 45 degrees F, and mean annual precipitation ranges from 12 to 24 inches. Frost-free period ranges from 90 to 140 days.
