A Tacoma snowshoer who had been missing in Mount Rainier National Park since Saturday was found alive yesterday. 66-year-old Yong Kim became separated from the group he was leading after sliding down a steep slope. The experienced snowshoer was well-equipped for a day’s outing, but had no overnight equipment. Despite temperatures in the teens and more than eight inches of new snow since Saturday, the rescue team reported Kim to be stable and alert when they found him. A park spokesperson said no hospitalization was necessary – and he has returned home.
