example 6

fine-loamy, mixed, superactive Typic Haplocryalf

This soil is found in southeastern Idaho at elevations of 6,600 to 8,000 ft. Associated native vegetation includes subalpine fir, Douglas-fir, myrtle pachystima, snowberry, and pine reedgrass. The soil is formed in loess overlying limestone residuum. Due to excessive leaching, calcium carbonate is present only in the lower-most horizons of the subsoil. These soils are used primarily for timber production; however, some land is also used for livestock grazing. These are not productive agricultural soils because of the short growing season.
