Permit M-1977-493—Climax Mine Technical Revision 37 (TR-37) <br /> Eyre Family <br /> The Eyre series consists of shallow, well drained soils that formed in material weathered from <br /> sandstone. Eyre soils are on mountain sides and have slopes of 5 to 60 percent. The average <br /> annual precipitation is about 20 inches and the average annual air temperature is about 38 <br /> degrees F. <br /> Reference Pedon: <br /> A representative pedon of this soil occurs in map unit 346C supporting aspen/Thurber fescue <br /> plant association on a 75 percent west southwest facing back slope at 9,100 feet elevation <br /> located in the SW 1/4, SE 1/4, sec. 23 , T. 4 S., R. 82 W., in Eagle County, Colorado. Taxonomic <br /> class: Loamy-skeletal, mixed Lithic Cryoborolls <br /> Oi -- 1 to 0 inches; undecomposed grass litter; abrupt clear boundary. <br /> Al -- 0 to 5 inches; gravelly loam, dark reddish brown (5YR 3/2) moist; weak fine subangular <br /> blocky structure parting to weak fine granular; very friable, nonsticky, nonplastic; many very <br /> fine and fine roots; many fine interstitial pores; 18 percent sandstone rock fragments; slightly <br /> alkaline; clear smooth boundary. <br /> A2 -- 5 to 12 inches; very gravelly loam, dark reddish brown (5YR 3/3) moist; weak fine <br /> subangular blocky structure parting to weak fine granular; very friable, slightly sticky, <br /> nonplastic; common very fine and many fine roots; many fine interstitial pores; 40 percent <br /> sandstone rock fragments; neutral; clear wavy boundary. <br /> Bw -- 12 to 17 inches; extremely cobbly fine sandy clay loam, red (2.5YR 4/6) moist; weak fine <br /> and medium subangular blocky structure; very friable, slightly sticky, nonplastic; few very fine <br /> and common fine roots; many very fine interstitial pores; 70 percent sandstone rock <br /> fragments; neutral; abrupt smooth boundary. <br /> R -- 17 inches; hard red sandstone <br /> Gateview Family <br /> The Gateview series consists of very deep, well to somewhat excessively drained soils that <br /> formed in alluvial or colluvial material from sedimentary rocks and glacial materials of mixed <br /> origin. Gateview soils are on outwash terraces, toeslopes, alluvial fans, till plains, kames, esters, <br /> mountains, and low ridges. Slopes are 2 to 40 percent. The mean annual precipitation is about 20 <br /> inches and the mean annual temperature is about 36 degrees F. <br /> Representative Pedon: <br /> A representative pedon of this soil is located in Gunnison County, Colorado; two miles south of <br /> Crested Butte, Colorado, in Sec. 12, T. 14 S., R. 85 W. Taxonomic Class: Loamy-skeletal, <br /> mixed, superactive Pachic Haplocryolls <br /> Al -- 0 to 9 inches; dark brown (10YR 4/3) gravelly sandy loam, very dark brown (10YR 2/2) <br /> moist; moderate fine granular structure; slightly hard, very friable, non-sticky, non-plastic; many <br /> fine and very fine, few medium roots; many fine and very fine interstitial pores; 20 percent gravel; <br /> medium acid (pH 5.9); gradual wavy boundary <br /> Exhibit I —Appendix A I-A-45 March 2024 <br />
