Starting at Mill Creek, this route brings you up to storm pass to elevations above 12,000 feet. You then follow ridge lines to the East and North where you top out at over 13,000 feet on West Elk Peak. A long descent brings you down past Costo Lake to the Mill Creek Trail. After a short jaunt on Mill Creek Trail, you split off onto the Lowline trail for the final segment which wraps around back to your starting location.
