• Exhibits "J" & "K" • <br />VEGETATION AND GENERAL INFORMATION <br />West Tennessee Sand and Gravel Pit <br />Chuck Ldebster <br />This pit is located approximately 6z miles northwest of Leadville. <br />Elevation is approximately 10,300 feet. The mining site and planned <br />areas of expansion are gently sloping topography. The natural top- <br />ography and aspect should have little affect on reclaimation efforts. <br />The average annual precipitation recorded at Leadville is 18.48 inches. <br />The average frost free season is 7° days. Plant growth is limited by <br />the short growing season and cool temperatures. The average annual <br />temperature is 36.2 degrees F and average minimum temperature through <br />the summer is only 35.7 degrees F at Leadville. Climatic factors should <br />be similar at the mine site. <br />Two general vegetative types occurr on this site. The vegetation <br />along k'est Tennessee Creek affected by a high watertable and the higher <br />upland site dominated by Iodgepole pine. These two types correlate <br />directly with the soils map furnished. Vegetation along West Tennessee <br />Creek (mapped as Marsh, P1(,) is affected by a high watertable. There <br />is a dense cover of willows, sedges, rushes, and tufted hairgrass on <br />this area. <br />The higher, upland site (mapped as Troutville, TrE) is dominated by <br />a relatively dense stand of lodgepole pine. Avery sparce understory <br />includes scattered plants of kinnickinnick, Western yarrow, junegrass, <br />elk sedge, buckwheat, shrubby cinquefoil, common juniper, and fireweed. <br />
