"THE CHURCH -- this is the only off trail entity i will mention. you will see it every time you go up heaven's gate lift. it is the rock outcropping skier's right. you can't miss seeing it. now, the church is holy ground, mecca, in your adventure in skiing and riding. i only know of jon egan, the director of the ski school for having done this extreme terrain. it is a 30 foot cliffdrop into trees. i know more have done it, but that doesn't include me. you really, really, really better know what you are doing.
