Two were killed a few days ago in a 2007 Bonanza leaving Aspen. One was low time but the other pilot an ATP! It's always the same old sad story. The climbed up a canyon in trying to clear the high ridges to the east. The lowest possible pass is 12,000'. The rule is very simple: always circle climb well above the highest terrain any where near your route BEFORE starting to cross. Never try to out climb the terrain.
