Profile

The name “Threebear” is derived from a creek in Latah County, Idaho. These soils are on hills with slopes of 5 to 35 percent.
Threebear soils are used mainly for timber production and wildlife habitat. The potential natural vegetation is western redcedar, grand fir, Douglas-fir, western larch, and western white pine. The average annual precipitation is about 36 inches (900 mm), and the average annual temperature is about 42 °F (6 °C).
