One of my two favorite places on earth is Hanging Lake, which is up Deadhorse Canyon. Deadhorse is itself off Glenwood Canyon through which run both the Colorado River and I-70. Hanging Lake is about a mile up Deadhorse Canyon, and "hangs" about a good 500-600 feet up the canyon wall (the whole hike has an elevation gain of 1,100 feet). This picture is taken from a boardwalk over the lake. The edge of the lake which I'm standing over is just a few inches from the cliff edge.
Just off I-70, about 10 miles east of Glenwood Springs, CO (my home town). If you visit during the summer, I recommend packing breakfast and going very early in the morning as Hanging Lake now gets up to 100,000 visitors a year.Colorado | Glenwood Canyon | Glenwood Springs | Hanging Lake
