It's early August, 2012, Robber's Roost is in full swing. The valley of Las Vegas is deep in the throes of the summer swelter. The Mt. Charleston is considerably cooler than the sizzling pavement of the lower elevations. Even though the temperatures are lower, the air varies from crisp to humid over the course of a single climbing day. On this day, Jonathan Groppenbacher attempts The Burglar. He is being belayed by the route's first ascentionist, Leo Henson.
