BARX SERIES
The Banc series consists of very deep, well drained soils that formed in alluvium and reworked
eolian material derived from sandstone. Barx soils are on alluvial fans, terraces, hills, and mesas.
Slopes range from 0 to 15 percent. Mean annual precipitation is about 11 inches and the mean
annual temperature is about 49 degrees F.
