Pistol River flows generally southwest for 21 miles (34 km) to the Pistol River State Scenic Viewpoint overlooking the Pacific Ocean near the community of Pistol River, about 17 miles (27 km) north-northwest of Brookings and 10 miles (16 km) south of Gold Beach, Oregon. The stream originates at an elevation of 3,179 feet (970 m) on the southern flank of Sugarloaf Mountain and drains a watershed of 67,200 acres (27,195 ha) in the Siskiyou National Forest. It is named after a pistol reportedly lost in the river by a militia soldier, James Mace, in 1853. The floodplain of the Pistol River consists of Quaternary sediments transported from the Southern Oregon Coast Range. The sediments in the Pistol River watershed are derived from rocks in the Franciscan Complex, formed during the Jurassic and Early Cretaceous periods, about 200 to 100 million years ago. The Yolla Bolly terrane is well represented in this area, consisting mainly of sandstone, mudstone, and conglomerate. The unconsolidated sediment in the lower river reach contributes to the historical channel shifts across the broad floodplain. The archaeological record of Chet-less-chunn-dunn, a village of the Pistol River band of Tolowa people, suggests it was moved repeatedly, likely in response to the shifting river channel.

The people of Chet-less-chunn-dunn were among several groups that spoke the Chetco Tolowa language, part of the Athabascan language family. They became involved in the Rogue River Wars, an armed conflict from 1855 to 1856 between the U.S. Army, supported by local militias and volunteers, and Native American tribes commonly referred to as the Rogue River Indians. The conflict was preceded by numerous skirmishes, starting as early as the 1830s, between Euro-American settlers and Native Americans over land and resources. In March 1856, a decisive battle against the settlers occurred, known as the Battle of Pistol River. A group of 34 volunteers was besieged for several days in an improvised log fortress by Tolowa warriors. Eventually, the village of Chet-less-chunn-dunn was burned to the ground, forcing the Tolowa people to relocate to reservations in Oregon and California. In central coastal Oregon, the Tillamook, Siletz, and about 20 other tribes, along with the Tolowa, were resettled at what is now known as the Siletz Reservation. This reservation is located on land along the Siletz River , about 15 miles (24 km) northeast of Newport, Oregon.

The Oregon coast is characterized by some of the highest wave energy in the world. The predominantly north-south orientation of the coastline, the absence of offshore islands to dissipate storm wave energy from the North Pacific, and the limited presence of erosion-resistant bedrock all contribute to relatively high rates of coastal erosion. This erosion leads to sediment transport, while constant onshore winds drive dune formation at the mouth of the Pistol River, between Crook Point to the south and Cape Sebastian to the north. The shifting river channel through the dunes has created numerous pothole ponds that attract waterfowl and shorebirds. The river supports populations of Chinook and coho salmon, steelhead, and coastal cutthroat trout. It generally flows through forests where industrial logging has damaged fish habitats. Efforts to restore these habitats are ongoing. Pistol River State Scenic Viewpoint is a park acquired between 1962 and 1969 through purchase and litigation from various owners. In 1964, one tract was donated to the state by Maytor H. and Vari McKinley of Los Angeles, California. Read more here and here.
