New Mexico's Gila National Forest
This was a trail called "Purgatory Chasm Trail" and we expected much more than we got, but it was still pretty awesome. We walked in between the canyons for a long time. It looked like this was where the water rushed when it rained because all of the rocks in the canyon were so smooth. We had to turn around because the sun was setting and we were not prepared for the dark. We did make it to the top of the trail for a bit though before the sun set.
