JR. Falls is an extremely technical and consequential Class V+ waterfall drop on the Moxie Stream, featuring a narrow, boulder-choked entrance that leads to a near-vertical 15-foot plunge with minimal margin for error. Paddlers must execute a precise entry through a tight, offset slot with significant hydraulic potential, carefully navigating multiple submerged rocks and a potential sticky hole at the base of the falls. Extreme caution is required, with a recommended scout and potentially a portage, as a mistake here could result in severe injury or worse.
