A mother and her youngest child have been discharged from a Nevada hospital a day after being rescued with four other group members from a bitter cold mountain wilderness.

Doctors say the father and three other young members of the couple's families who spent two days in sub-zero temperatures also are doing well but will remain for observation at a hospital in Lovelock about 100 miles northeast of Reno.

Doctors say some members of the group suffered from slight exposure and dehydration, but none had frostbite.  He credited James Glanton with keeping alive his girlfriend, Christina McIntee, their two children and a niece and a nephew of McIntee.

The 34-year-old mine worker and hunter built a fire just minutes after their Jeep rolled down a snowy embankment on Sunday and kept it going until rescuers found them about noon Tuesday.
