I ended up passing the turn off to head up to Mummy Mountain and kept following the North Loop and made it all the way to Lee Peak on accident. From up there I could tell where I was supposed to go and decided to head over to Mummy Mountain and still get it done on the same day. It's a steep trek up there though! When the trail gets to big hillside of scree and there a couple really long switchbacks, the trail will keep going along the hill side and there will be a cairn on the right hand side of the trail where the trail goes pretty much straight up the hill on some really loose scree. It's a grind to get up it but it's really fun to come back down! It's almost like skiing down the hill side on the scree!
