Horizon Description <br /> The soils as examined are similar throughout the area and vary only with <br /> respect to depth. They may be defined as a typic Cryoboroll as derived from <br /> Mancos shale. There is an insignificant layer of dark organic matter followed <br /> by an A horizon dark brown in color (10 YR 2/1). The A horizon is vari- <br /> able in depth, but is about 1 foot deep over the area. This is followed by a <br /> 61 horizon which extends in places to about 2.5 feet deep. This is dark in <br /> color (10 YR 2/2) and varies only slightly from the A horizon. This B1 <br /> horizon overlies a C horizon which consists of Mancos shale fragments inter- <br /> spersed with Bl material. The average depth of the soil to the C horizon is <br /> about 20 inches. If this value is multiplied by the area involved, the volume <br /> of soil in question may be derived. <br /> The entire horizon is derived from the Mancos shale. It is friable, <br /> strongly blocky and cemented. Drainage is moderate. Based on these <br /> conclusions, the soil could be easily revegetated should it be disturbed. <br /> Respectfully submitted by: <br /> Soltesco Soil and Water Consultants <br /> Daniel F.
