SAN FRANCISCO (AP) — Two skiers who disappeared near Lake Tahoe during a winter storm were rescued Monday morning after they burrowed into snow caves and huddled together for warmth, authorities said.

The two men, described as expert skiers, were spotted by the crew of a Placer County Sheriff's Department helicopter about seven miles from the Alpine Meadows ski resort, just west of Lake Tahoe.

Patrick Frost, 35, and Christopher Gerwig, 32, both of San Francisco, were picked up near Hell Hole Reservoir, department spokeswoman Kelly Hernandez said.
