an increase in summer residents has occurred due to development and sale of ranchettes in the <br />area. Big game hunting in the region, particularly trophy elk hunting, is also an important land <br />use and source of income to many of the local ranchers and outfitters. <br />Permit Area <br />The Lorencito Canyon mine is situated on 3142 acres of private land southeast of the town of <br />Weston, Colorado. The 7.5 minute series topographic map of the Little Pine Canyon Quadrangle <br />depicts the majority of the permit area. Elevations within the permit area range from 6600 feet <br />above mean sea level in the northeast part of the permit area to 7350 feet in portions of the <br />southern permit azea. Steep slopes and rugged canyons generally describe the topography of the <br />permit area. With the exception of relatively, narrow, flat canyon floors of Lorencito and Cow <br />Canyons, most of the permit azea is dissected by V-shaped side drainages to the main canyons. <br />These drainages are rimmed by steep, rocky outcrops, and watersheds are divided by narrow, <br />sharp ridges. Four main canyons are situated within the permit boundary. Cow Canyon bounds <br />the permit area on the west. Lorencito Canyon and Little Jeff Canyon are located in the eastern <br />portion of the permit area. Jeff Canyon runs west to east through the center of the permit azea <br />and Puertecito Canyon bounds the permit area on the south. Surface mining activities will <br />generally be focused in Lorencito Canyon and on the north ridge of Jeff Canyon. <br />Land use of the permit area is dominated by rangeland/wildlife habitat. Ninety-nine (99) percent, <br />or 3117 acres, of the permit area is, by Coal Regulation definition, rangeland/wildlife habitat. <br />Cropland and irrigated cropland occupy 25 acres, mainly along the Purgatoire River alluvial <br />valley floor. <br />In addition to the two main drainages within the permit area, Lorencito and Cow creeks, <br />numerous other drainages exist within the permit and adjacent area. Chimney, Jeff, Puertecito, <br />Little Pine, Bonita, Alamosa, and Little Alamosa creeks all drain areas within the permit and <br />adjacent area. Only Lorencito creek demonstrated perennial flows during the baseline collection <br />period. Minimum flows at all other sites were recorded as zero at least once during the baseline <br />period. <br />Lazge flows occur down ephemeral drainages in response to intense precipitation events, <br />typically during the months of July, August, and September. A flow of 240 cubic feet per second <br />was recorded at the mouth of Little Pine Canyon. Snowmelt contributes only a small percentage <br />of total runoff, as infiltration and sublimation likely account for most of available snowmelt <br />waters. <br />Soils in [he permit area are thin, and in places, non-existent. The exception is the valley bottoms, <br />where soils are moderately well developed. Clay loam, with a low infiltration rate, describes the <br />majority of soils in the azea. <br />Vegetation in the permit area is dominated by an oak/pinyon community. Most of the land in the <br />permit area, with the exception of the canyon bottoms and a few small grassland meadows, <br />would be rated poor for suitability as rangeland. <br />
