The term gate, from the Anglo-Saxon geat, or opening, can refer to a valley through a low range of hills, a broad opening between hilly areas, a defined section of a river, hence Hellgate Canyon on the Rogue River near Medford, Oregon, or an opening to a bay or harbor between promontories, hence the Golden Gate in San Francisco Bay. A gate is grander in scale than a gap. Golden Gate is more than a mile wide between the Marin headlands and Fort Funston, and the two portals for which Gates of the Arctic National Park is named, Boreal Mountain and Frigid Crags, frame an opening five miles wide across the Koyukuk River in Alaska’s Brooks Range.
