3. Xerorthent landscape
Latah Co., Idaho

The moderately sloping to steep slopes of this landscape are characterized by what is known as patterned ground, a microtopography consisting of mounds and intermounds. Xerorthents are found in the intermound areas while deeper Xerolls are found in the mounds. This patterned ground may have formed as a result of differential erosion during the ice age when the climate was much colder. Frozen soil was less susceptible to erosion and was left behind, forming the mounds.

The intermound soils are very shallow to basalt bedrock and have limited use.
