Longtime local climber/developer/writer Peter Beal is going to lead an informative tour on the bouldering of Flagstaff Mountain on May 1st. Info here: Mountains and Water: Bouldering Tour at Flagstaff Mountain May 1. Here is a link to a video of Peter climbing one of Flagstaff’s gems: Mountains and Water: Smith Overhang V8
Peter has been climbing for a super long time, and is responsible for many hard and some unrepeated routes in the front range like the famous Primeval (5.14a) at Primo Wall in Clear Creek Canyon and the unrepeated The Agony and The Ecstasy, 5.14a (originally given 13d, but upgraded after nobody repeated it for over 10 years), at Lower Security Risk Crag in Boulder Canyon.
And since this seems to be the Peter post, I should note that Peter also has an website (not recently updated) that records Boulder Canyon Bouldering info: Boulder Canyon Bouldering Guide.
