January 20, 198 UNITED STATES DEPARTMENT OF AGRICULTURE SOIL CONSERVATION SERVICE Norwood Field Office PO Box 488 Norwood, Colorado 81423 suo~ecr: Resource data for mine reclamation permit; oaTe:January 25, 1978 Mine tivest of Carnation Mine - Gyp Valley To: A~r~. Charles Ponchak Pioneer Uravan Po sox 2065 Grand Junction, Colorado 81501 Dear Mr, Fonchak: __ This will constitute the Soil Conservation Service soils and vegetative report for a ne~•+ mine site e:est of the Carnation I~;ine in Gypsum Valley. I am enclosing a copy of the general soils map of the Dolores River Easin that v+as prepared by the SCS, I believe I gave you a copy of the soils map for use in your original pez•mit request for the Carnation and Geo 1-,fines, This copy is provided in case you have misplaced the other, or submitted it with your first permit request, kppa.rently it has been pretty well recieved by the State ];fine Reclamation Board. I~Iy field visit to the property today confirmed that the site falls into rnapping unit ~r'3 as shoe+n on the Dolores River Easin report. The soil unit is comprised of fairly steep terrace breaks above alluvial fans as described in mapping unit ~3, The slopes are about 25 to 30% except for the flatter terrace area. T}~ere is over 35%a Pock and rock fragments scattered throughout the soil and on the surface v+hich will make it difficult to stockpile any topsoil for reclamation purposes. I completed a vegetative inventory on an area which r+as staked as being a "portal entrance" to determine e+h at the potential native vegetation might be. The existing vegetation, % ground cover and est;mat>ed production is shown on the attac}~ed form CO--RkI•:GE-6. The area is a complex of Rockland and Pinyon-Juniper l"ioodland la.,id types. Pock outcrops and those rocks scattered about make un mound 35% of the surface area, The Pinyon and Juniper canopy is about 30%, Total annual production could be a.s high as 150 pounds per acre. Since a commercial source of seed for the native plants listed is eithc-r non-existant or extremely ev.pensive you may wish to consider the follolving mixture and seeding ra.~e per acre of each species for revegetation: Noz-dan crested wheatgrass - 3 lbs; yellow sweetclover - 2 lbs; and either 7 lbs of Jose tall erheatgrass or 4 lbs of Paloma Indian ricegrass, You may wish to scatter three or four pounds each of mountain mahogany and four-wing saltbush to break up the outline.
