Dear Buck,
In response to your request for soils and revegetation/
reclamation information concerning the Robinson Brick Company
(Tomahawk) clay mine, located in the SW 114, Section 36, T. 18 S., R.
67 W., several observations and recommendations in summarized,
narrative form follow. These are based on our on-site inspection
conducted with Gary Belew, Fort Carson Range Conservationist, and
staff on November 21, 1990. The quarry site is operated under a
perpetual lease agreement and easement from Fort Carson (U.S. Army)
by DFC Ceramics, Inc., with the latter as operator and responsible
for final reclamation.
As depicted on the enclosed soils map of the area in question, the
major soil of potential impact is the Travesilla-Rock outcrop complex
• (coded TrG on the enclosed soils map of the area). In non-outcrop
areas, the texture of the surface soil is a sandy loam to a gravelly
sandy loam, overlying hard sandstone at an average depth of
approximately 14 inches. General aspect is basically west-southwest,
with moderate to steep (20-90%) slopes. The soil is gravelly and
stony on the surface, with extensive areas of previous mining and
associated surface disturbance apparent.
The soil is more fully described in the additional enclosures, which
include tables describing potential uses, chemical properties,
limitations and hazards Ci.e. soil and site suitability for various
purposes), and significant engineering properties. Please note that
these properties are typical of the NATIVE, UNDISTURBED Travesilla
soil in the area, and may not be representative of the reworked,
subsoil backfill material. Other than mining and special purpose use
by Fart Carson, the soil is probably best suited for livestock
grazing and wildlife habitat.
From a revegation/reclamation standpoint, the native soil would
exhibit limitations, chief of which would be shallow topsoil layer,
high mineral and low organic matter content, possibly poor compaction
characteristics (depending upon amount of clay material in final
backfill), and dry, open slope exposure. For purposes of mining or
excavation, the soil, subsoil and parent material are relatively
