OASIS IN THE DESERT! At mile 8 of our rim-to-rim hike we decided to venture on a side trail to a genuine oasis in the desert. It's called Ribbon Falls and it was 1/2 mile off our route. I love this spot! It was a great place to unload our packs and take a 30 minute break. I was able to crawl into the cave as well as submerge myself into the invigorating crystal clear water. Check out this 1 minute video & listen to Dr Walp quickly explain the formation at the bottom of the falls.
