We did this climb during the first week of May, 1992. I don't believe this is the best time to climb Half Dome. It was probably too early in the season and we simply got lucky. We're east coasters and didn't realize how bad the weather can get up there early in the season.
Ignorance is bliss.
The way we climbed it, VI 5.9 C1 . Feel free to send updates to me . NW face of Half Dome, Yosemite Valley. Attempting to climb this route can get you injured or killed. Conditions of the route will and do change.
