A couple of recent off-season additions/renovations will boost the winter-time experience at Squaw Valley, Calif. The resort has replaced the uber-popular Shirley Lake detachable quad with a high-speed Doppelmayr six pack (the new lift will follow the traditional line, loading and unloading at the usual spots). The Riviera superpipe, which has been dug out of the ground, will be surrounded with lights, giving Squaw the only night-time access superpipe in the Tahoe area.
