The Tebo series consists of very deep, well drained, moderately permeable soils that formed in glacial till high in basalt. These are on glaciated uplands and have slopes ranging from 1 to 65 percent. The mean annual temperature is about 52 degrees F. and the mean annual precipitation is about 65 inches. Tebo silt loam, on a south facing 10 percent slope under coniferous forest at 410 feet elevation.
All textures are apparent field textures.
The particle size control section is 10 to 35 percent coarse fragments and 27 to 35 percent clay. Angular basaltic pebbles and cobbles as well as smooth glacial pebbles are throughout the profile. The soil is medium acid to very strongly acid. The soil is dry for 45 to 60 days following the summer solstice. It is silt loam, gravelly silt loam or gravelly clay loam and has 5 to 10 percent rounded and angular pebbles.
