Most of the material is brown or tan, but there are other colors and some nice mossy pieces. Be careful not to stray onto private land. Most of the land between the sites is private. While you are this close, you really should go to Hell's Backbone. This unique spot is a knife-edged ridge with a narrow bridge at the top.
Sheer walls drop off both sides for hundreds of feet.
For years, mail and supplies were carried to and from Boulder over this bridge. It is a sight to see, but visitors might want to close their eyes while crossing the bridge. Assuming you made it safely across, you might as well go on to Blue Spruce and Posey Lake. If you are lucky enough to make this trip in the fall when the leaves are turning, you will be rewarded with some of the most beautiful scenery in the state. You can also try hiking up the trail behind the Blue Spruce Campground.
