As others said, "Little Gem"
Fantastic in the snowy season. Getting to Windy Gap usually requires spikes or crampons and axe, but it's well worth the effort. There's also year-round running water at Little Jimmy Springs. Right by PCT. And also close to another Gem. South Mt. Hawkins, but that one is unorganized, you'll have to search for a place for your bivy to lay if you set up there.
I've been to Jimmy multiple times in dirt, snow, and even a little rain. It's not overly windy, because it's protected by a bunch of trees. The peaks and saddles around it can get a little windy.
