From the Tom's Thumb Trailhead two of my friends and I set off up to Morrell's Wall and did some very intense scrambling up a large chimney in Morrell's Wall. After topping out on Morrell's we continued up a bowl that had a very long boulder field up to the top that we scrambled up. From there it was a moderate hike to the top of East End where the ammo box is. We then scrambled up the very shear rocks, from the east side of them, to the point where you see in the picture
