The Lamont series consists of deep, well drained, moderately rapidly permeable soils formed in eolian deposits on uplands and high stream benches. Slope ranges from 0 to 45 percent. Mean annual temperature is about 50 degrees F, and mean annual precipitation is about 32 inches. Solum thickness ranges from 30 to 60 inches or more. Carbonates generally are lacking to depths of many feet.
Lamont soils range from medium acid to strongly acid in the most acid part.
The A horizons having value of 3 typically are less than 5 inches thick. The A horizon is fine sandy loam, sandy loam, or loam. Undisturbed pedons have a weakly expressed E horizon that has hue of 10YR, value of 4 or 5, and chroma of 2 or 3. Some mottles of high chroma are in the E horizons and throughout the B horizon in some pedons. The BE and Bt horizons have hue of 10YR or 7.5YR, value of 4 to 6, and chroma of 3 to 6.
