40-year-old Eric Abney and his 13-year-old son Chase were missing after going on a snowmobile trip Sunday. However, after an extensive search by rescue crews and volunteers, a snowmobiler on a tour in the area spotted Chase. About a half hour later rescue crews were able to locate his father who had left for help about an hour earlier. Both the father and son are in good condition. They made a snow cave with a floor lined with tree branches. Deschutes County Captain Shane Nelson said if it were not for the snow cave they might not have survived the night.
