Permit M-1977-493—Climax Mine Technical Revision 37 (TR-37)
<br /> The Moran series consists of very deep, well drained soils on mountain slopes, mesa summits,
<br /> and footslopes. They formed in slope alluvium, colluvium, and till. Slopes are 0 to 70 percent. The
<br /> mean annual precipitation is about 45 inches, and the mean annual air temperature is about 32
<br /> degrees F. Taxonomic class: Loamy-skeletal, mixed Typic Cryumbrept
<br /> Reference Pedon:
<br /> A representative pedon of this soil occurs in map unit supporting curly sedge/Alpine clover plant
<br /> association on a 45 percent southeast facing backslope at 11,337 feet elevation located in the

<br /> Quander family
<br /> The Quander series consist of very deep, well drained soils formed in slope alluvium and
<br /> colluvium derived from andesite, rhyolite, trachyte, breccia, or tuff. These soils are toeslopes,
<br /> footslopes, and backslopes of ridges and mountains. Slopes range from 5 to 65 percent. Mean
<br /> annual precipitation is about 20 inches and the mean annual temperature is about 38 degrees F.
