How much snow is there in the Sierra right now? Here's what Yosemite National Park says about its two high elevation campgrounds:

There’s still lots of snow in the high country, so we’ve changed the tentative opening dates for Tuolumne Meadows Campground and Bridalveil Creek group sites from July 15 to August 1. We will not be accepting reservations for dates prior to August 1 for these two campgrounds for now. The campgrounds could still open earlier. We’ll provide updates once we make a determination (we won’t know for a few months, at least).
Tuolumne Meadows is at about 8500-9000 feet, while Bridalveil is a bit lower, at 7200 feet. Most of the trails in the Sierra a higher than this.
Plan accordingly. We've schedule our first trip for about a month later than we usually do, and we're still concerned that we might not be able to make it.
