6.
fine-loamy, mixed, superactive Typic Haplocryalf

This soil is found in southeastern Idaho at higher elevations. Parent material is loess overlying limestone residuum. Leaching is facilitated by the cool, moist climate and has moved calcium carbonate to considerable depth. This has allowed clay to move and accumulate in the argillic Bt horizons. Textures are silt loam in the E horizon and silty clay loam in the Bt horizons.

These are not productive agricultural soils because of the short growing season. Primary land uses are timber production and watershed; however, some land is also used for livestock grazing.
