SOILS <br /> <br />Soils Classification and Overburden <br /> <br />The soils of the basin are derived from both the harder crystalline <br />rock forming the spine of the Gore Range and the sedimentary deposits of <br />the Minturn and Maroon Formations. In general, the residual soils east <br />of the Gore Fault are very meager and often barely or do not cover the <br />underlying crystalline rocks. The residual soils within the area of the <br />Minturn Formation are somewhat deeper although the soils tend to be <br /> <br />coarse-grained since they are derived mainly from the coarser sandstone <br /> <br />and conglomeritic members of the formations. <br /> <br />The General Soil Map of Eagle County, prepared by staff members of <br /> <br />the Soil Conservation Service, U.S. Department of Agriculture, is. as the <br />title indicates. a very generalized map of the soils within the area. <br />This map indicates only four soil types within the Gore Creek basin. <br />These soil associations and descriptions thereof are: <br /> <br />48 <br />50 <br />98 <br />168 <br /> <br />Description and Percent Extent <br /> <br />Rock Outcrops - Cryumbreats - Cryuquepts <br />(45%, 35% and 20%) <br />Cryoborolls - Cryoboralfs - Rock Outcrop <br />(60%, 30% and 10%) <br />Cryoboralfs - Cryoborolls - Rock Outcrops <br />(60%. 20% and 20%) <br />Haploborolls - Argiborolls - Eutroboralfs <br />(40%. 35% and 25%) <br /> <br />Soil No. <br /> <br />These generalized soil associations are not sufficiently detailed <br /> <br />in character to be utilized to a great degree without additional field <br /> <br />investigation. The permeability indication for the four soil associa- <br /> <br />tions is for the Haploborolls - Argiborolls - Eutroboralfs association <br /> <br />and is moderate. slow and moderate. respectively. <br />
