2.04.9 <br />• RESPONSE continued <br />all horizons. The Cryorthents were mostly considered Lithosols <br />and Regosols in the 1938 classification as modified in 1949. Most <br />of them in the United States still have their native vegetation <br />(1). <br />The Starman soil series belongs to the Lithic Cryorthen sub- <br />group. <br />Lithic Cryorthents <br />These soils have a lithic contact within 50 cm of the soil surface <br />and commonly at a depth appreciably less than 50 cm. The soils <br />may be saturated with water above the lithic contact when snow <br />melts, but because the water is cold and is moving down the <br />slope, reducing conditions are too weak to produce mottles of low <br />chroma. This lithic subgroup is also allowed to have permafrost. <br />• Where rock is shallow, ice wedges and lenses must be thin or <br />absent (1). <br />SOIL CHEMICAL AND PHYSICAL PROPERTIES <br />The mine property was broken into two sampling units. Land <br />north of County Road 53 was sampled by the soil scientist at <br />Yampa Mining Co. and land south of the road was sampled by <br />VTN Colorado, Inc. <br />The soil test results from the south side which were analyzed by <br />Colorado Analytica] Labs are shown in Table 1 and the soil <br />sampling depths for each horizon are illustrated on Table 2. <br />The analyses show a pH range of 6.5-8.2. There doesn't seem <br />to be any trend of pH through the profile except that the A <br />horizon appears to have been leached as evidenced by a slightly <br />lower pH. The electrical conductivity of the soils range from <br />. 0.3-1.1. From these results none of the soil horizons have high <br />enough concentrations of salts to affect even the most salt sen- <br />sitive plants. The organic matter content is very high. This is <br />
