Breaks
Upland soils with more than 20 percent slopes and broken by canyons or gullies. This site
is found on steep escarpments and canyon-like areas. The slopes may have occasional benches. The
slope profile consists of rock outcrops and deep soils that occur between the rock outcrops. Runoff is
high. The site contains forbs, grasses, legumes, shrubs, and scattered trees. The vegetation was formed
under migratory grazing and heavy impact from bison and other native wildlife, with fires in both the
dormant and growing season.
