Big Timber Creek in Montana is an extremely steep and challenging whitewater kayaking destination, characterized by a series of high-volume waterfalls and technical slides. The experience requires a significant commitment, beginning with a steep, one-mile hike while shouldering kayaks to reach the put-in rapid. The run features several named, high-consequence rapids. No Worries Falls is a double-stage drop exceeding 20 feet in height. The Pinch is a 100-foot slide with three rolling kickers that constricts to barely a boat's width at its exit, demanding precise control at high speed. The final and most formidable feature is Big Timber Falls, an intimidating cascade that plummets nearly 80 feet in a series of drops; its entry includes a 30-foot waterfall into a pool, followed by a fast exit through a slot leading to another 12-foot slide onto a kicker flake. The overall character of the creek is one of intense, expert-level whitewater, with a crew-based "dirtbag" ethos focused on chasing high-flow conditions. The season for running this creek is spring or early season, as referenced by groups aiming to be among the first descents of the year. Hazards are severe and inherent to the steep, committing nature of the run, including complex waterfalls, tight constrictions, and powerful hydraulics.
