BOX 471 <br />LAMAR, COLORADO 81052 <br />FEBUARY 17, 1987 <br />Soils in this area are shown on Soils Sheet no. 28 (attached)-they <br />are La-Las loam O to lx slopes and Lv-Lincoln sand O to 1~ slopes. <br />La-Las loam-surface soil is a grayish-brown loam 10 to 20 inches <br />thick; subsoil is a grayish-brown to dark-gray loam or clay loam and <br />is at a depth ofi 36 to 40 inches. The substratum is generally <br />stratified loam or clay loam, but in many places it is sandy and <br />gravelly I~etween a depth of 36 and 60 inches. <br />Lv-Lincoln sand-surface soil is a brown or grayish-brown loamy sand <br />or light 'sandy loam about 5 to 10 inches thick. Normally, the <br />subsoil and substratum are stratified with lenses of sandy loam and <br />sand. DeF~th to the underlying sand and gravel ranges from about 16 <br />to more than 60 inches. These soils are a good source of gravel and <br />sand for concrete and road fill. <br />This area was used as irrigated cropland in the past, however it is <br />presently in a non-use state being allowed to return to a native <br />condition.. The present plant po?ulation consists of approximately <br />10% (by w1:.) Sand Dropseed, 90x Kocia, Russian thistle, Tansy Nusi.ard <br />and other annual weeds and grasses. <br />If the plainned land use is to be Wildlife Habitate following gravE~l <br />mini^~ operations then the top foot of soil should be stockpiled <br />during the: mining operation and returned as top soil to the site <br />following c._~mpletion of the gravel mining. Where stockpiles will be <br />stored for long periods, they should be seeded to protective cover. <br />Small grains such as wheat, barley, and or sorghums may be used a~. <br />temporary cover. <br />When reclaiming the site following the mining operation the steeper <br />slopes should be 3 to i or flatter. One foot of topsoil should be <br />returned to all disturbed areas of the site (includeing steep slopes) <br />and a seecl mixture similar to that shown on Form CO-ECS-S (attached) <br />should be planted to establish a permanent cover. <br />Since r~j/e~l/y~,~. ~ <br />i :S'~<<~ <br />OHN L.
