At least 17 youths and adults were back home Saturday evening after being treated for frostbite and exposure suffered during a cross-country ski trip near Elk Meadows Ski Resort in Beaver Canyon.

A registered nurse at Beaver Valley Hospital in Beaver said Saturday night that three of the 17 were admitted to the hospital but later released.Individuals in the group went to the hospital throughout Friday night and early Saturday, the nurse said. Members of the Beaver County Sheriff's Search and Rescue group, some traveling on snowmobiles, were among those involved in helping to assist the group.

Norman Jones, Young Men president, Nephi North Stake, The Church of Jesus Christ of Latter-day Saints, said those injured were among a group of 75 youths and leaders on a trip to a lodge at the Beaver High Adventure Base.

Jones said the group encountered 20 degree below zero temperatures. "The trip ended up being a much more strenuous trek than we had expected."
