More to be done on this story, but for now, just some photos. Note the difference between the Start and End photos:

The Team, smiling and in good shape before the climb.

The Great Roof, an incredible formation.

Belaying from top of Texas Flake, not a care in the world.

 

David coming to a ledge; note the amount of air below. The white triangle of rock below is the low angle, lower half of El Cap, terribly foreshortened. The trees are about 2000 ft below.

Coming over the rim at the top, with the ground 3000 ft below. To my right, just at the edge of the rock, is a road; the miniscule dots are cars.  

The Team at the end, back on the Valley floor. Note that we have traces of smiles but are visibly worse for the wear. Five nights, six days (oft 18 hr days) later, usually finishing by headlamp.
