We didn't take highway 84 to 155 but approached from other direction so that is probably why we didn't find the mosque and entrance. So we exited 84 and started back in and took first left thru unmarked road and drove back, I was a bit apprehensive since I wasn't sure this was really a road but my husband drove on. Finally we parked and got out-WOW it was incredible. We were the only people around and the cliffs were so very different, the white color on the blue sky and their appearance of dripping. We really enjoyed this very unusual setting. So while we were not at the actual entrance we were there.
