Cosmogenic burial dating results, detrital zircon U-Pb results, and knick point locations associated with the incision history of Hells Canyon

This data release is companion to a manuscript entitled: "Carving North America’s Deepest Gorge: Constraints on the Timing and Mechanism of forming Hells Canyon". Here, we report cosmogenic age data analyzed from sediments deposited within caves within the Hells Canyon region, as well as the knick point locations mapped out from topographic analysis and detrital zircon U-Pb ages derived from cave samples.
