UNITED STATES DEPARTMENT OF AGRICULTURE SOIL CONSERVATION SERVICE '"'Canon City. C sue:ECr: Descriptions of soils and vegetation DATE: 6_3p-77 on quarry sites To: ~Colonna and Company of Colorado, Inc. Canon City, Colo. Attn: Dennis Burbank, Genre al Manager Dear Sir: In response to your request of soil and vegetation descriptions for the three quarry sites, we have the following to report: The soils in the areas of the Canon Cream and the Byzantine - quarries are similar, These are the Rentsac very channery loam, 20 to 50 percent slopes. The profiles are very chan- nery to extremely channery loam with bedrock within 20 inches over most of the area. The profile is calcareaus, pH range is 8,0 to 8.4. Permeability is moderate and available water capacity is low. Vegetation consists mainly of pinon-juniper trees and grasses, mainly blue grama. I think that after shaping and grading the spoil areas as much as possible, planting pinon and juniper trees along the base of the cliff and grasses over the rest of the area can be made successfull~r. The soil around the area of the Mica Lode quarry is a shallow, well drained soil. The soil name i-'s~osant, rock outcrop is complex, 15 to 50 percent slopes. The profile is very gravelly sandy loam surface layer about 4 inches thick, The subsoil is extremely gravelly heavy clay loam about 12 inches thick. Fractured granite is at a depth of about 16 inches. The pro- file is noncalcareaus. Permeability is moderate and avail- able water capacity is low. Native vegetation consists mainly of pinon and juniper trees with an understory of shrubs and grasses. Some cholla cactus is also present. I believe a successful planting of pinon and juniper trees, shrubs and grasses can be made on the spoil areas after shaping and grading. Sincerely, .c.s..L_ by Awb Lynn S.
