• Resources, Inc. , in the Coal Basin area. The proposed subsidence study area <br /> is located in both Pitkin and Gunnison Counties, Colorado. <br /> The proposed subsidence monitoring site over the multi-lift longwail <br /> panels is a very remote and rugged mountainous area. Elevations in the <br /> monitoring area vary from approximately 11,000 ft to 12 ,000 ft (Figure 2) . <br /> The overburden section above the coal seam is approximately 2000 to 2500 ft <br /> in thickness. <br /> Site Access: <br /> The Coal Basin area is reached by a paved road that extends from Redstone, <br /> Colorado to the Coal Basin Mine Office. From there, well maintained dirt <br /> haulage and access roads extend to the various mines in the Basin. <br /> The proposed subsidence monitoring area is accessed by a foot trail that <br /> • begins on the haulage and access road near the No. 5 line. The subsidence <br /> monitoring area lies approximately 1.5 miles from, 'and 2000 ft in elevation <br /> above , the No. 5 Mine road. Walking time from the No. 5 ;line road is about 3 <br /> hours. <br /> Site Conditions : <br /> The proposed site location is in a rugged mountainous area that is par- <br /> tially forested. The area lies entirely within the White River and Gunnison <br /> National Forests.. The construction of access roads to the area is impossible <br /> because of county and U.S. Forest Service regulations. Because of this, the <br /> study area can be accessed only by foot, horse or helecopter. <br /> Because of its extremely high elevation, and severe winter weather, the <br /> • proposed monitoring area will be inacc­.>sable 'uring the winter. 'death... <br /> and snow cover prohibit field work from October through the middle of June. <br /> 1 <br />
