Just got back from a short trip to Yosemite, and some of the weirdest weather I had experienced.
Arrived Monday - beautiful spring day. Tuesday morning was clear and brisk, but about 11:30am, some clouds came in and within an hour it was hailing! A few hours later it was snowing!
So that night was in a Curry tent cabin (heated, fortunately). The annoying thing about that is, of course, you have to go out to use the restrooms that are a few hundred feet away. But hey, you just have to bundle up well and brave the cold and the bears.
Oh yeah, Curry was crawling with bears that night. Saw two myself that night, another the next morning. First time in maybe a dozen visits to the park that I actually saw a bear.
Morning was beautiful - the meadows, cars, etc. had a light dusting of snow. But it got warm quickly and by noon it was mostly gone.
Overall a great visit.
