<br /> <br />;; <br />, <br />k <br /> <br />A wide range of soil conditions exist in the WSA but <br />generally they are moderate in inherent fertility <br />and erosion hazard. Some of the more fertile soils <br />are reflected in the areas of high productivity for <br />potential timber management. Mass movement potential <br />is apparent in the slide rock areas. <br /> <br />4. <br /> <br />Minerals <br /> <br />The Sangre de Cristo WSA contains numerous evidence <br />of past and present mining activity. Past mining <br />activity has been concentrated in the southern end <br />of the area from Mosca Pass to Blanca Peak and in <br />the northern end, north of Hayden Pass. There are <br />pending mineral lease applications as of May 1, <br />1982, covering about 102,300 acres of the WSA, as <br />shown on Figure 5. Lease applicatons on the Bureau <br />of Land Management lands are not shown. <br /> <br />Approximately 53 percent of the area has high or <br />moderate potential for locatable minerals. The area <br />with high potential is generally at the northwestern <br />end of the study area. Only 5 percent of the area <br />is considered nnlikely to have any mineral <br />potential. Recent exploration activity has occurred <br />along mnch of the lower elevation areas on the <br />eastern side of the range. Exploration activity on <br />the western side of the range occurs from the lowest <br />elevation areas to the crest of the mountains with <br />the maj ori ty of the claims located between Hayden <br />Pass and Crestone Peak. There are 684 unpatented <br />claims on the Rio Grande National Forest portion. <br /> <br />~ <br /> <br />Table D and the Mineral Potential Map, Figure 6, <br />shows mineral information, derived as a part of the <br />Forest planning process. <br /> <br />36 <br /> <br />(,("0064 1 <br />\.)... ,t. <br />
