Soilscape south of Monument Valley; northern Arizona
Foreground: Sheppard-Massadona-Monue complex, 0 to 10 percent slopes.
The Sheppard series consists of very deep, somewhat excessively drained soils that formed in eolian material derived from sandstone. Sheppard soils are on structural benches, alluvial fans, dunes on structural benches, and terraces. Slopes range from 0 to 60 percent. Mean annual precipitation is about 9 inches and the mean annual air temperature is about 54 degrees F.
TAXONOMIC CLASS: Mixed, mesic Typic Torripsamments (No diagnostic features)
USE AND VEGETATION: These soils are used for livestock grazing. Potential vegetation is Mormon-tea, Indian ricegrass, galleta, and Russian thistle.
DISTRIBUTION AND EXTENT: Southeast Utah, northern New Mexico, northern Arizona, and southwest Colorado. LRR D, MLRA 35. This series is of large extent.

The Massadona series consists of very deep, well drained soils that formed in alluvium derived from shale. Massadona soils are on hills, toeslopes, and alluvial fans. Slopes range from 0 to 12 percent. Mean annual precipitation is about 10 inches and the mean annual temperature is about 47 degrees F.
TAXONOMIC CLASS: Fine, smectitic, mesic Typic Haplocambids
USE AND VEGETATION: Monue soils are used for livestock grazing. Vegetation is galleta grass, Indian ricegrass, spike dropseed, winterfat, and sand dropseed.
DISTRIBUTION AND EXTENT: Southeastern Utah and northern Arizona.

The Monue series consists of very deep, well drained, moderately rapidly permeable soils on stream terraces, fan terraces, and eolian deposits on structural benches. Monue soils are formed in alluvium and eolian materials from sandstone. Slopes are 1 to 15 percent. The average annual precipitation is about 7 inches (178 mm) and the mean annual air temperature is about 54 degrees F (12 degrees C).
TAXONOMIC CLASS: Coarse-loamy, mixed, superactive, mesic Typic Haplocambids
USE AND VEGETATION: Monue soils are used for livestock grazing. Vegetation is galleta grass, Indian ricegrass, spike dropseed, winterfat, and sand dropseed.
DISTRIBUTION AND EXTENT: Southeastern Utah and northern Arizona.

Background: Torriorthents-Rock outcrop complex, 25 to 65 percent slopes. Torriorthents are the dry Orthents of cool to hot, arid regions. They have an aridic (or torric) moisture regime and a temperature regime warmer than cryic. Generally, they are neutral or calcareous and are on moderate to very steep slopes. A few are on gentle slopes. Many of the gently sloping soils are on rock pediments, are very shallow, have a sandy-skeletal particle-size class, or are salty. Others are on fans where sediments are recent but have little organic carbon. The vegetation on Torriorthents commonly is sparse and consists mostly of xerophytic shrubs and ephemeral grasses and forbs. The vegetation on a few of the soils is saltgrass. Torriorthents are used mainly for grazing. They are extensive in the Western United States.
Rock outcrop are miscellaneous areas that have little or no identifiable soil and thus supports little or no vegetation without major reclamation. They are exposures of bare bedrock. If needed, map units can be named according to the kind of rock, e.g., “Rock outcrop, limestone.”
