Columbia Rock Viewpoint
Looking east across Yosemite Valley to Half Dome from the Columbia Rock viewpoint, roughly a mile up the trail from the second trailhead.
The dropoff here is steep, but there are iron guardrails for the brave to lean on.
The top of North Dome
just visible near the left edge of the photo. The
Mirror Lake trail
leads into the valley underneath the face of Half Dome,
and the Mist Trail
(Nevada and Vernall Falls) heads away into the valley off to the right of Half Dome.
