I've posted a video with scenes shot at Mel-High in 1972. It's on my profile page, but I figured not everyone would happen on it there.
If the YouTube link doesn't work for you.
Thanks to David Allsopp for taking, preserving and rediscovering those old movies.
P.S. I'd still like to know who the mystery girl is. She's in the video. I'll update it to give her a proper title card if someone can tell me who she is. There are a few other unidentified people in there also. Any ideas?
