NONTECHNICAL SOILS DESCRIPTION REPORT
Rocky Mountain Materials - Schnurr, Stephen J.
Map Soil name and description
Symbol
The Manvel soil is deep and well drained. It formed in
alluvium. Typically, the soil is silt loam or silty
clay loam. Permeability is moderately slow. Available j
water capacity is high. Effective rooting depth is 60
inches or more . Runoff is slow to very rapid, and the
hazard of erosion of unprotected soil by water is
slight to very high.
66 Manvel silt loam, 3 to 8 percent slopes
The Manvel soil is deep and well drained. It formed in
alluvium. Typically, the soil is silt loam or silty
clay loam. Permeability is moderately slow. Available
water capacity is high. Effective rooting depth is 60
inches or more . Runoff is slow to very rapid, and the
hazard of erosion of unprotected soil by water is
slight to very high.
71 Midway clay loam, 3 to 15 percent slopes
The Midway soil is shallow and well drained. It formed
in residuum derived from shale. Typically, the surface
layer is clay loam 3 inches thick. The upper 6 inches
of the substratum is clay. The lower part to a depth
of 16 inches is extremely shaly clay. Highly,
fractured clay shale is at a depth of 16 inches .
Permeability is slow. Available water capacity is very
low. Effective rooting depth if 6 to 20 inches .
Runoff is medium to rapid, and the hazard of erosion of
unprotected soil by water is moderate to high. This
soil has high shrink-swell potential . -
72 Midway-Cascajo complex, 10 to 40 percent slopes
This map unit is on moderately sloping to steep ridges,
knobs, hills, and edges of old, high terraces deeply
dissected by streams. It is about 60 percent Midway
soil and about 20 percent Cascajo soil . The Midway
soil is mainly on steeper side slopes . The Cascajo
soil is mainly on knobs and hills and along crests of
terrace edges .
