In 1878, during a U.S. Geological Survey of the park, Henry Gannett, a geographer working with the survey, named a peak just two miles southwest of Mount Washburn in honor of Lord Dunraven and the service his book had done for the park. In 1879, Philetus Norris, the park Superintendent, gave a pass on the Grand Loop Road between Tower and Canyon the name Dunraven Pass because of its proximity to Dunraven Peak.
