Description
Mammoth Rock is a technical Class II rapid featuring a large midstream boulder that splits the river flow and creates a series of reactive eddies and small pourover holes. Paddlers should aim for the river right channel with a clean line between the central rock and the right bank, taking care to avoid potential pin spots and maintain momentum through the constricted water. The rapid demands precise boat positioning and quick maneuvering, particularly during lower water levels when rock features become more pronounced.
