No representative from <br />MINREC, Inc. was present. Weather conditions were overcast and 8 inches of snow was on the ground. The <br />access road to the mine was not plowed and it was inaccessible. The temperature was warm and I was getting <br />concerned that the snow may become slippery. Pictures were taken from a vantage point overlooking the mine. <br />AVAILABILITY OF RECORDS — Rule 5.02.4(1): <br />All the necessary records were in the records room at the Garfield County Courthouse in Glenwood <br />Springs.
