The Threebear series consists of moderately well
drained soils formed in silty sediments with a thick
mantle of volcanic ash. These soils are moderately
deep to a fragipan. 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 red cedar, grand fir, Douglas fir,
western larch, and western white pine.



The average
annual precipitation is about 36 inches, and the
average annual temperature is about 42 degrees F.
