A month late, but still interesting! Here's a panoramic view, courtesy of the New York Times, of the pipe at Stratton, along with some audio commentary from Pat Malendoski, of Planet Snowtools.
The related article, which you can find here, probably belongs in the snowboarding forum, but oh well.
Anyone have any other pics on how they build halfpipes? I'd love to see how one is formed. I've seen the special Cat attachments for grooming a halfpipe, but do pipes have a wood or metal base to shape the formation, or are they "all-natural?"
