Canyonlands - first stop was Shafer Canyon Overlook. The whole time I've wanted to know what is natural vs what has man messed with. These roads were used originally to move animals. They would sometimes fall to their death the roads were so narrow. Yikes. When the mining came to town the roads were widened and made for larger trucks. That stopped when it became part of a national park. (If you want more history-I highly recommend Google, or traveling out here to read the signs.)
