LRU notes
Major land resource area (MLRA): 043C-Blue and Seven Devils Mountains
Modal LRU – 43C04 Dissected Basalt Highlands
This LRU is composed predominantly of mid elevation slopes of foothills, mountains and canyon walls. The soils tend to be loamy Argixerolls and Haploxerolls with minor ash influence in the surface layer. Colluvium and residuum from basalt are the dominant parent materials. Soil climate is a frigid temperature regime and xeric moisture regime with median annual precipitation of 890 mm (35 inches).
Others where occurring – 43A02 – Eastern High Basalt Plateau
Ecological site concept
This ecological site occurs mainly on forested backslopes of mountains and canyon walls. Parent materials are derived from basalt rock mantled by volcanic ash and loess.
