It was a frightening fall at Crater Lake National Park, and it took rescuers six hours to bring the man to safety. The Associated Press reports that Eric Brimlow, 27, from Syracuse, New York jumped into the snow, over the rock barrier Tuesday around 10:30 a.m. Parks spokesperson Marsha McCabe says Brimlow slipped 300 feet down rocks, snow and gravel, before being stopped by two trees he was pinned between. She says the lake was still another 400 feet or so: “The lesson is: please respect the boundaries we have set up. Please stay behind the rock walls that we have established around the rim and in other developed areas. Please respect any barriers we've put up whether they are ropes or signs we've put up. Crater Lake is an incredibly beautiful, very steep and very unstable so you need to enjoy it from a safe location." Dozens of park personnel and other emergency crews conducted a high angle technical rescue, again taking 6 hours. Brimlow was taken by helicopter to Rogue Valley Medical Center.
