<br /> <br />3. PRE-tQINING LAND USE <br />Mine Site <br />The Henderson Mine is located very near the headwaters of <br />the West Fork of Clear Creek. Access to the valley is restricted on <br />three sides by surrounding mountains. The "box canyon" type of <br />situation made the valley a popular site for bootleggers in days gone <br />by because the single-direction access allowed easy detection of <br />approaching revenuers. <br />Several mines were actively prospected in Clear Creek <br />C~ <br />Valley. The Puzzler Mine, located just up from Berthoud Falls, is <br />still periodically operated in search of silver and gold. The Jean <br />Mine and the Doctors Group of mines are located above the Henderson <br />Mine in the Clear Creek watershed. The Urad Mine, a molybdenum mine <br />located on Woods Creek, was operated by various companies through the <br />years, the last of which was AMAX. The Urad ore body was depleted and <br />the mine closed in 1974. Final comprehensive reclamation of Urad is <br />well underway. <br />More recently, the canyon held a number of mountain cabins <br />and was described as "rapidly becoming a mountain slum" by a member of <br />the environmentalist community. Most of these cabins were removed <br />from the area during the initial stages of development. <br />The Henderson ore body was discovered in 1965 as a direct <br />• <br />result of AMAX geologists exploring the possibility of "another Urad <br />ore body." Initial diamond drilling revealed no such ore body, but <br />the drilling provided geologic information indicating the possibility <br />of much deeper mineralization. Permission was granted for "one last <br />hole," which -- according to projected geologic modeling -- was <br />5-1 <br />
