Longs Peak, 1996
3. The Trough. Much earlier in the hike we saw a couple people wearing hard hats. It seemed odd at the time, but when we got to the trough we knew why. This is the part of the hike I thought was the most dangerous. People up ahead were knocking loose small rocks, and they picked up quite a bit of momentum as they rolled down the trough. Notice the bull's-eyes painted on the rocks to help guide hikers along the best path.
