Catwalk, Gila National Monument, NM (3341)

The Catwalk National Scenic Trail had originally started out as a line that brought water from the mountains down to a mill in the valley. In 1935 the CCC (Civilian Conservation Corps) made it into a walk way, and it has since been upgraded to meet modern accessibility standards.

It's fairly popular, but well worth the hike.

Best viewed as part of New Mexico set.
