The name says it all. Much of Telluride's ski mountain is dauntingly "steep and deep," but its signature run -- ominously named the Plunge -- transports lionhearted experts from 12,000-foot heights almost straight down to the picturesque village below -- and very quickly, too. Take your pick, hotshots: Half of this harrowing run is carefully groomed, the other half infested with knee-twisting moguls. For the daring, this matchless winter challenge is well worth an eight-hour drive from downtown Denver. Why? Because it's there.
