You can pull off the road on the right about 1 mile after you start up Kane Springs Road. This small parking lot is the beginning of the Amasa Back Bike Trail. If you look up at the sandstone monolith across the creek, you can see a large alcove about half way up it that looks like an eye. Just to the left of the eye is one of the deserts many secrets, the "Owl Panel".
The best light for this location occurs around the spring and autumnal equinox. So the months of March and September would be a good time to try it. The cooler temperatures will of course would make for more comfortable hiking on the return trip. Be sure to take plenty of water as there is no good source of water on the route.
