This was a partial inspection of the Colowyo Mine conducted by Jim Stark of CDMG. The inspection was conducted on 27 March 2006. Tony Tennyson of CCC accompanied me on the inspection. The mine was actively mining coal, hauling coal to the Loadout and loading a train at the time of the inspection. The weather was warm and sunny and much of the ground was muddy (with shady areas still covered with snow). Roads: -The access road and haul road to the Gossard Loadout is a paved road. The road was well maintained and in good condition. -The light-use road to the West Pit and East Taylor ponds was muddy and slightly rusted at the time of the inspection. The road was still stable and overall in good shape, given the conditions. -The haul roads in the East and West pit areas were all well maintained and stable at the time of the inspection. The roads were dry. No erosional problems were noted on these roads. -The light-use roads around the Gossard maintained and in good condition.
