Here a short film from David Mason climbing at Horsetooth Reservoir, Colorado. I made the first ascent of Moon Arete way back in 1991 when I went there with Christian Griffith. This was a time when bouldering wasn't really recognised and 1st ascents not always named which was the case with this problem. I don't really remember much about the ascent and it didn't bother to name it and it was probably Christian who called it Moon Arete. It nice to see it's become such a classic problem.
