Tommy Caldwell and Kevin Jorgeson are free-climbing almost 3,000 feet up El Capitan, basically with their fingers. The New York Times shows the ascent with a route placed on top of a 3-D model. Scroll in a WebGL-enabled browser on the biggest screen possible for a smidgen of feeling for what the climb is like.
See also Caldwell’s Facebook page for some amazing pictures of what they’ve experienced so far.
Update: The Times just published a high-res image of the wall. Click on the links in the caption to see Jorgeson, but a tiny speck.
