Description
Gilsum Gorge is a powerful Class IV rapid featuring a technical boulder-strewn descent with multiple mandatory moves through a narrow, steep constriction. Paddlers must navigate a series of sharp hydraulics and tight rock walls, with significant consequences for missed lines and a high risk of pin or wrap scenarios if not executed precisely.
