For episode No. 4 in GearJunkie’s “Off The Map” video series, sponsored by Yakima, we travel to western Minnesota in search of some of the most obscure rock climbing on the continent. The episode, “Bouldering the Great Plains,” highlights the unlikely and rare rock — and the rare climbers who pursue it! — on a landscape dominated not by mountains but wheat fields, dirt roads, and old farms. Climb on!
