Date: April 16, 2004
Location: Sec. 9, T1N;
R102W. 6th PM
Situation: You requested an inventory of the existing soil and vegetation
for a proposed new gravel pit located in West Johnson Draw, Section 9, T1N,
R102W and approximately 2 miles south west of Rangely, Colorado. You also
requested recommendations for reclamation of the site once the mining is
completed.
Information Provided: The site is presently in an undisturbed condition with
limited roads present and has been primarily used for grazing by livestock
and wildlife.
1) SOILS - Two soil units occur on this site, 21 Cliffdown-Cliffdown
Variant complex, 5 to 65 percent slopes and 46 Kinnear fine sandy loam,
1 to 5 percent slopes.
Soil Mapping Unit 21 - Cliffdown-Cliffdown Variant complex, 5 to 65
percent slopes occurs on the perimeter area of the pit. This map unit occurs
on terrace side slopes. The Cliffdown portion of this complex has slopes of
5 to 8 percent. It is a deep and somewhat excessively drained soil formed in
calcareous alluvium. The surface layer is typically a gravelly loam about 5
inches thick. The underlying material to a depth of 60 inches or more is a
calcareous very gravelly sandy loam with a thin strata of very gravelly loamy
sand. Permeability is moderately rapid. Available water capacity is very
low. The effective rooting depth is 60 inches or more. Runoff is medium to
slow.
The Cliffdown-Variant is moderately deep and well drained. If formed
in calcareous, gravelly and cobbly alluvium derived from mixed sources.
Typically, the surface layer is a very cobbly loam 7 inches thick. The next
6 inches is a calcareous very gravelly loam. The underlying material is
gravelly clay loam 11 inches thick. Weathered shale is usually found at of
depth of about 20 to 40 inches. Permeability is moderately slow. Available
water capacity is very low. Effective rooting depth is 10 to 20 inches.
Runoff is rapid and the hazard of water erosion is moderate to high.
Soil Mapping Unit 46 - Kinnear fine sandy loam, 1 to 5 percent slopes
is in the central part of the proposed pit area. This is a deep well drained
soil formed on fans and upland terraces. It formed in calcareous alluvial
and eolian material.
Typically, the surface layer is a fine sandy loam 5 inches thick. The
subsoil is a loam 12 inches thick. The upper 18 inches of the substratum is
a highly calcareous loam, and the lower substratum to a depth of 60 inches or
more is a loam. Gravel deposits underlie the soil at this site.
Permeability'is moderate and the available water holding capacity is high.
Effective rooting depth is 60 inches or more. Runoff is medium and the
hazard of water erosion is slight. The hazard of soil blowing is moderate
when the surface is disturbed and not protected from blowing.
