<br /> Scout family
<br /> The Scout series consists of very deep, somewhat excessively drained soils that formed in till,
<br /> colluvium, slope alluvium, and residuum from sandstone, conglomerate, basalt, quartzite, rhyolite,
<br /> andesite, and tuff. Scout soils are on mountain slopes, mesa summits, broad ridge tops, and spur
<br /> ridges and have slopes of 0 to 70 percent. Permeability is moderately rapid. The mean annual
<br /> precipitation is about 34 inches and the mean annual temperature is about 38 F.
<br /> Representative Pedon:
<br /> A representative pedon of this soil is located in the NE 1/4, NE 1/4, sec. 19, T. 8 S., R. 76 W., in
<br /> Park County, Colorado. Taxonomic Class: loamy-skeletal, mixed Typic Cryochrepts.
