The Quinault Canyon is a submarine canyon, off Washington State, in Olympic Coast National Marine Sanctuary. It lies opposite the Quinault Reservation. From the map, it is clear the Quinault River drains into the Pacific Ocean, opposite Quinault Canyon. The north of the Copalis National Wildlife Refuge is also a bit east, as are a few cities and sites, as Kalaloch, Queets, Taholah, Point Grenville (a headland), Moclips, and Pacific Beach. Also, Quinault, Washington and Lake Quinault are both onshore.
Quinault Canyon is 25 kilometres (16 mi) from shore, and is 378 square nautical miles in area.
All of the following submarine canyons are near, headed north to south:
Of local submarine canyons, Quinault canyon is deepest. Quinault Canyon has a maximum depth of 1,477 metres (4,846 ft).

Quinault Canyon has acted as a funnel for north- and northwestward-moving sediment along Washington’s continental shelf, and it is a major pathway between the continental shelf of Washington and deep sea. Silt and clay originating from the Columbia River move down Quinault Canyon.
