New Mexico ? Two snowboarders lost in the mountains were rescued by helicopter Tuesday after they endured three frigid nights holed up in snow caves that are credited with saving their lives.

Adam Putnam, 36, an emergency room physician and an experienced winter camper, and his fiancee, Rachel Fehl, 30, a nurse, suffered some cold toes and mild dehydration but were otherwise OK.

The pair spent a couple of hours at St. Vincent Regional Medical Center on Tuesday after a National Guard helicopter plucked them from a ridge where they had stomped SOS in the deep snow.

After two days of severe weather that kept the search on the ground, Tuesday’s clear and sunny skies allowed helicopters to look for the pair, who had been in intermittent cell phone contact with authorities since they got lost outside the Santa Fe ski area Saturday.

In Colorado, meanwhile, the search resumed for two Albuquerque snowboarders, Michael George and Kyle Kerschen, both 27, who have been missing near Wolf Creek Ski Area in southwestern Colorado since Saturday. Wolf Creek is about 170 miles southwest of Denver.
