AKA NORAD. I'm one of the few people ever to have climbed it on the East face - with permission anyway from all the commanders anyway

About 1980. Just look for the nest of antennas. They are hard to miss. The engineers that work the various sites up there must have a decent sense of humor...I recall a "Caution - Children at Play" sign up there nailed to a tree. I have a photo of it around here somewhere
