COMPETING SERIES: These are the
Ash Springs,
Crib
Decker,

Wodskow series.
Ash Springs soils have a mean annual soil temperature of 54 to 59 degrees F.
Crib soils have lithologic discontinuities with skeletal layers below 40 inches and have total(silicate + carbonate) clay greater than 18 percent.
Decker soils receive annual precipitation of 12 inches and have a shallower calcic at a depth of 11 to 20 inches.
Lind soils have greater than 18 percent total (silicate + carbonate) clay.
Wodskow soils have 5 to 15 percent Calcium Carbonate throughout the calcic horizon.
GEOGRAPHIC SETTING:
Parent material: eolian material and/or alluvium derived from sandstone, shale, limestone and quartzite
Landform: fan remnants and alluvial flats
