= 1 ;~ <br />.,,_,,, <br />• 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 A2 horizon dark brown in color (10 YR 2/1). The A2 horizon is vari- <br />able in depth, but is about 1 foot deep over the area. This is followed by a <br />Bl 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 A2 horizon. This Bl <br />horizon overlies a C horizon which consists of Mancos shale fragments inter- <br />spersed with Sl 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 />~J` ` <br />Soltesco Soil and Water Consultants <br />Daniel F.
