I know the arete you speak of. If you are hiking downhill on the Moses Spring Trail and you have just made the last switchback and are heading straight towards the Heffalump, look to your left and it is about 50 feet off the trail. I attempted the arete and my buddy climbed it. A lot of fun. On the back side of the arete is a nice problem with a dyno to a hidden two-finger pocket. Kind of sharp but doable for someone in better shape than me.
