Peter Iredale was a four-masted steel barque sailing vessel that ran ashore October 25, 1906, on the Oregon coast en route to the Columbia River. She was abandoned on Clatsop Spit near Fort Stevens in Warrenton about four miles (6 km) south of the Columbia River channel. Wreckage is still visible, making it a popular tourist attraction as one of the most accessible shipwrecks of the Graveyard of the Pacific.
The ship was named after Peter Iredale, who not only owned the vessel as part of his shipping fleet, but was also a well-known figure in Liverpool, England, where his business was headquartered.
The ship was built in Maryport in June 1890, by R. Ritson & Co Ltd for P. Iredale & Porter. She displaced 2,075 tons and measured 87 meters (285 ft) in length and was fashioned from steel plates on an iron frame. She had royal sails above double top and topgallant sails, and was the largest vessel built by Ritson. The ship was originally commanded by Captain G.A. Brown and later by Captain H. Lawrence.
Sailing from Salina Cruz, Mexico, on or about September 26, 1906, Peter Iredale was bound for Portland, Oregon with 1,000 tons of ballast and a crew of 27, including two stowaways. The voyage up the coast was unremarkable until the night of 25 October, when Captain H. Lawrence sighted the Tillamook Rock Lighthouse at 3:20 a.m. local time. The crew altered course first east-northeast and then northeast to enter the mouth of the Columbia River in thick mist and a rising tide. Under strong winds out of the west, an attempt was made to wear the ship away from shore, but a heavy northwest squall grounded Peter Iredale on Clatsop Sands (now called Clatsop Spit). High seas and wind drove the ship ashore. A lifeboat was dispatched from Hammond, Oregon and assisted in evacuating the sailors, who were tended to at Fort Stevens. No casualties occurred in the accident.
