Two different climbing groups got caught in a slide on Mt. Hood Thursday morning and a huge chunk of ice broke loose and knocked one woman onto the edge of a cliff. That’s according to fellow climbers who witnessed the event. “Perhaps we were about 100 yards west of the Hogsback and about 50 yards below the Bertram, they weren’t doing the standard route, they cam around the west side of Crater Rock.” That was one of Meredith Jakes, 30, climbing party, calling 911, after Jakes, who is from Hood River, was climbing Hogsback on Mt. Hood, when a large slide of snow and ice headed right towards them. “She was struck by a 20’ x40’ chunk of ice.” Clackamas County Detective Jim Stroving says she suffered face, neck and back injuries after being hit and then falling 300 feet. The Hogsback is a long and narrow knife-edge ridge beginning at about 10,000 feet on Mt. Hood, an area that often requires crampons and is the more technical section of the mountain's most popular, south face-climbing route.
