In this video by Jon Glassberg from Louder Than Eleven, we follow Chris Weidner and Bruce Miller on their attempt to establish a new route on The Diamond on Longs Peak, Colorado. Longs Peak is 14,255ft high, which makes The Diamond North America's highest elevation big wall.

Chris Weidner explains that he had spent 52 days working the route over four summers before committing to a redpoint. The pair opt for different days for their individual redpoint attempts and the film covers Chris' push.

The difficulty of the individual pitches ranges from 5.11d (7a) to 5.13b (8a) and there is often extra difficulty dealing with the alpine temperatures found at that altitude. In the film, Chris deals with frozen fingertips, pumped toes and a stunning granite line.
