Salmon fishermen dubbed this section of the Dennys River "Hell's Vestibule". Named after the flat rock on which naturalist John James Audubon observed the demolition of a temporary dam across the river in the late summer of 1832, unleashing a wall of water to lift and free the logs piled up in the rocky gorge below, and described in his essay "The Force of the Waters." Ray Robinson noted that this is the least fished portion of the river, although anglers have occasionally succeeded here.
