Right now Wildrose has early spring conditions. A friend did it a couple of weeks - the day after we'd done Corkscrew - and reported no snow at the kilns, and only scattered patches in the sheltered drainage leading to the ridge. However ... the past several weeks have been unusually mild, and that appears to change soon. This is a good site to get more info on the impending weather.

I'd re-post that question a bit closer to your trip. Wildrose and Fall Canyon are on my short list of mid-week hikes over the next few weeks. Mainly waiting for the wildflowers to hit their stride in DV before doing them.

Ever consider doing Surprise Canyon/Panamint City, just north of Ballarat?
