<br /> Handran Family
<br /> The Handran series consists of very deep, well drained soils that formed in thick stony deposits of
<br /> alluvium and glacial material and material weathered from granite, basalt, sandstone, and shale.
<br /> The Handran soils are on alluvial fans, moraines, mesa tops, and valley filling side slopes. Slopes
<br /> are 0 to 75 percent. The mean annual precipitation is about 20 inches and the mean annual
<br /> temperature is about 38 degrees F.
<br /> A representative pedon of this soil is located in Jackson County, Colorado; approximately 500
<br /> feet east and 200 feet north of the SW corner of Sec. 24, T. 11 N., R. 81 W.. The Handran Series
<br /> is classified as Loamy-skeletal, mixed, superactive Ustic Haplocryolls
<br /> A-- 0 to 9 inches; grayish brown (10YR 5/2) very stony loam, very dark grayish brown (10YR 3/2)
<br /> moist; moderate medium and fine granular structure; soft, very friable, non-sticky, non-plastic;
<br /> common fine and very fine roots; many fine interstitial pores; 15 percent gravel, 15 percent
<br /> cobble, 15 percent stone; neutral (pH 7.0); clear wavy boundary.
<br /> Bw-- 9 to 35 inches; light yellowish brown (10YR 6/4) extremely cobbly sandy loam, dark
<br /> yellowish brown (10YR 4/4) moist; weak fine and medium subangular blocky structure; soft, very
<br /> friable, non-sticky, non-plastic; common fine, very fine, and medium roots; many fine interstitial
<br /> pores; 30 percent gravel, 25 percent cobble, 10 percent stone; neutral (pH 6.8); gradual wavy
<br /> boundary.
<br /> C -- 35 to 60 inches; very pale brown (10YR 7/4) extremely stony sandy loam, yellowish brown
<br /> (10YR 5/4) moist; massive; soft, very friable, non-sticky, non-plastic; few fine roots; many fine
<br /> interstitial pores; 25 percent gravel, 20 percent cobble, 25 percent stone; neutral (pH 6.8).
<br /> Hechtman
<br /> The Hechtman series consists of shallow, well drained soils that formed in material weathered
<br /> from rhyolite beds. Hechtman soils are on nearly level to steep mountain sides. The average
<br /> annual precipitation is about 50 inches. The mean annual temperature is about 34 degrees F.
<br /> Taxonomic class: Loamy-skeletal, mixed Lithic Cryochrepts
<br /> Reference Pedon:
<br /> A representative pedon of this soil occurs in map unit 245D in the Lincoln Creek watershed;
<br /> supporting lodgepole pine/grouse whortleberry plant association on a 53 percent southwest
<br /> facing slope at 10,000 feet elevation located in the SW 1/4, NW 1/4, sec. , T. 0 S., R. 80 W., in
<br /> Pitkin County, Colorado:
