Collins, CO 8051:2 <br />RE: Reclamation of N[ining Area (GLASS, John F., Sr.) <br />Dear Mr. Manley: <br />~02 ~~~ <br />1980 <br />- The area, northwest of the city of Ft. Collins, to be mined in <br />Mr. Glass's request is presently in irrigated cropland, but has the <br />soils found in the major range sites of Overflow and Wet Meadow, as <br />shown on the map.. <br />The Overflow Range Site here consists of level soil that is loamy <br />alluvial, moderately deep, with sands and gravels at depths of 40 inches. <br />Water tables occur seasonally at depths of 40 to 60 inches. The Wet <br />Meadow Range Site has finer texture of clay loam alluvial soil with sand <br />and gravel at depth of 12 to 40 inches. This soil is somewhat poorly <br />drained and has seasanaly water table occurring at depths of 24 to 40 <br />inches. Soils of both range sites would be classed as "prime land." <br />The potential native vegetation of these range sites would include: <br />9witchgrass, Big bluestem, Indiangrass, Western wheatgrass, Side-oats <br />grama and Blue grama. <br />When reclaiming the mined area, the topsoil should be stockpiled <br />and then used to cover the spoiled areas at depth of 12 inches or <br />greater. Any part not leveled should have slopes of 3:1 or flatter. <br />If irrigation is not used for starting vegetation, then new seedings <br />should be mulched with straw to improve the chances for success. This <br />will help prevent wind erosion and shade the ground to help retain <br />moisture. 4000~k/A c. of long strew should be anchored immediately after <br />distributing with mulcher blades that will not cut the straw. <br />A dryland mixture of grasses I would recommend is; <br />Thickspike wheatgrass (Critana) <br />Side-oats grama (Vaughn) <br />Switchgrass (Nebr. 28) <br />(cont.) <br />S~~FPLS /A c . <br />2'yd~PLS /A c . <br />L~~PLS /Ac. <br />9 ~~PLS/Ac.
