The Rogue River begins at Boundary Springs on the border between Klamath and Douglas counties near the northern edge of Crater Lake National Park. Near the mouth of the river, the only dinosaur fragments ever discovered in Oregon were found in the Otter Point Formation, along the coast of Curry County.

Beginning near Crater Lake, which occupies the caldera left by the explosive volcanic eruption of Mount Mazama, the river flows through the geologically young High Cascades and the older Western Cascades, another volcanic province. Known for its salmon runs, whitewaterrafting, and rugged scenery, it was one of the original eight rivers named in the Wild and Scenic Rivers Act of 1968.
