Jonathan Siegrist has spent his climbing life travelling the world and sending hard sport climbs, becoming one of the world’s best. In this film filmmaker Nate Liles explores the reasons why Jonathan has decided to spend so much of his recent time in Las Vegas. Jonathan climbed the first ascent of One Hundred Proof in February 2020, grading it a grade of 5.15a. The route is located in the Clear Light Cave on Mount Potosi. One Hundred Proof is likely the eighth 5.15 line in the United States. Siegrist has climbed half of them.
