Idaho Exposure

I can see the East Ridge of Mt. Cramer and it looks straightforward. The summit is on the skyline, about 1/3 toward the center from frame right. I've set a turnaround time of 4 pm, which is rapidly approaching. I figured 4 hours up, 2 hours down. That leaves me some wiggle room. I violate this by pushing the turnaround to 4:30 pm.
