Greys soil and landscape
The Greys series consists of very deep, well drained soils that formed in loess and silty alluvium from loess. Greys soils are on hills, fan remnants, terraces, moraines, mountain slopes, and footslopes of mountains. Slopes are 0 to 30 percent. The mean annual precipitation is about 530 mm and the mean annual air temperature is about 2.5 degrees C.
TAXONOMIC CLASS: Fine-silty, mixed, superactive Alfic Argicryolls
Mollic epipedon thickness: 25 to 40 cm
Depth to argillic horizon: 40 to 60 cm
Depth to secondary carbonates: greater than 127 cm
Particle size control section total clay: weighted average 18 to 27 percent
Soil moisture regime: udic
Mean annual soil temperature: 3.3 to 7.2 degrees C. (cryic soil temperature regime)
Mean summer soil temperature: 5 to 8 degrees C and where an O horizon is absent 10.0 to 15.0 degrees C.
USE AND VEGETATION:
Major uses: woodland, woodland pasture, and some cleared areas are cultivated with wheat and barley
Dominant native vegetation: aspen with an understory of pinegrass, wild rose, snowberry, timothy, and mountain brome
DISTRIBUTION AND EXTENT: Distribution: Southeastern Idaho, and Western Wyoming, MLRA 13 and 43B.
Extent: the series is moderately extensive
