Mammoth Rock

Mammoth Rock is a technical Class IV+ boulder garden with multiple complex lines that demand precise boat placement and quick maneuvering between large, closely-spaced rocks. Paddlers must navigate a series of powerful hydraulics and tight slots, with the primary route requiring a committed approach through a narrow, boulder-choked channel that can quickly punish hesitation or incorrect angle. The rapid's centerline contains a potentially sticky hole at medium to high water levels, making scouting and careful route selection critical for safe passage.
