Break On Thru To The Other Side
You should have a map and GPS. There are many side roads, stick to the directions. DEEP SAND.
Bring a flashlight.
Getting to the trailhead is an adventure in itself. From the trailhead hike about one hundred yards. Follow the BLM arrow left and climb up the ridge then right go around the corner to the left. A cave opening is ahead. This is a natural cave( tunnel) created in sandstone by water eroding from above. The tunnel is about 200 yards long and it curves so you can't see straight thru it. A good flashlight will be a big help. The ceiling can be low in sections. When you get to the other side the distant views are awesome as water and wind has further carved the landscape. You can return from here or continue exploring. There is evidence of art least nine partial caves starting to be formed from this side of the mountain. Each worthy of exploring for rock art. The walls are full of cowboy art, Indian art, and just plain graffiti. Explore to your heart's content.
