30 feet of snow a year
Thankfully not all at once, but Mammoth Lakes gets tons of snow throughout the winter. That makes the region a great place for fun and sports, most of which involve moving across that powder at high speeds: down the slopes on skis (or sleds and tubes!), across the fields on snowmobiles and fat-tire bikes, or coasting above the whole thing in a helicopter like a rich guy.
But maybe you’re tired of speed, having just left the rat race behind. Slow it down; snowshoeing is fun, and cross-country skiing is plentiful with a dozen trails ranging from "easy, breezy" to "difficult, but still breezy, because it is winter on a mountain, gang."
