The Mount Harney loop was described in a book that Mike A. had as a 8-9 mile loop. It was actually around 14 miles. So we being the smart ones we are we didn't plan on doing more than described. We didn't bring a filter to get water from the streams so we all ran out of water on this trek. We didn't carry our full packs, just day packs and water bottles. We started at the Willow Creek Trailhead and made our way along the marked trail. The trails were very well maintained and this route proved to be easy to moderate. Outside of the unexpected distance and our water situation this was a nice hike. The top of Mount Harney has a structure that used to be a look out for forest fires. Very interesting history. The living quarters and the pumphouse still have wire in the conduit from when it was installed. This trek was done on Thursday of our trip.
