Thunderbolt to Underhill Couloir

June 20, 2010 - The descent from Thunderbolt to the Underhill Couloir. We couldn't find any rapp stations at the 5.6 chimney, but the downclimb is straightforward, with one short 7-10 ft 5.6 bouldering crux midway down.

The chimney is a good option

When we did this downclimb in June after a snowy winter, the chimney route seemed a much better option. It did not seem quite 5.6 on the downclimb - some somewhat tricky moves but never with much exposure.
