Today's run took me from Coal Bank Pass up the Pass Creek Trail to the Engineer Mountain Trail. From the intersection I headed north heading for the white Creek Trail and the Colorado Trail. The first 3 miles were spent climbing through tall pines, occasional snow in the shade, and frquent slick ice on the trail disguised below dirt and footprints. After reaching the base of Engineer Mountain, the trail stayed entirely above treeline, about 12,000 feet, with constant undulations but nothing too drastic. This was all new trail for me, and every corner greeted me with new peaks and wilderness. Much of the trail is deeply rutted into the tundra, and the descents amd footing proved to be precarious in spots. I ran about 6 miles in about 56:00 and retraced the same 6 miles back to the truck in about 48:00. Total time = 1:44:15 for 12 miles.
