It's a relatively clear winter day here in Antelope, and from my office windows I can see the snowy peaks of the Sierra Nevada. The mountains are obscured in the summer, when our air becomes smoggy and hazy and brown. But during the winter, we're given wonderful views of the mountains on many days. Our church sits on the crest of a hill, enhancing the view.
I don't have links to any webcams that show this particular part of the Sierra, but if you're needing to view some true California snow, then check out this link to some views of Yosemite National Park.
