Description
Boss Moss is a powerful Class V waterfall rapid in the Moss Canyon section, featuring a massive recirculating hole that demands precise boat control and expert-level skills. Paddlers must navigate a tight entry with minimal margin for error, avoiding the infamous "big daddy hole" that can easily flip or hold boats, making clean line selection critical for safe passage through this technical drop.
