Altoona, Washington

For the mountain and rock in the English Lake District, search under Pillar (Lake District) Pillar Rock is a pillar-like monolith in the Columbia River, near its mouth in the state of Washington. Originally rising 75-100 feet, it was dynamited and reduced in height to about 25 feet above the water to serve as a navigational aid and light. The Lewis and Clark Expedition camped twice near the rock, on November 7 and November 25, 1805. The name "Pillar Rock" also refers to a small village on the river's north shore, opposite the rock. As recently as 1851, the village was home to a small group of the Kathlamet band of Chinook Indians under the headship of a man named Tolillicum.

Brookfield was a salmon-canning and fishing town located on the Columbia River in Wahkiakum County, Washington, United States, from 1873 to 1957. It was the home of the J.G. Megler Company.

Lewis and Clark National Wildlife Refuge, near the mouth of the Columbia River, provides wintering and resting areas for an estimated 1,000 tundra swans, 5,000 geese, and 30,000 ducks. Other species include shorebirds and bald eagles. Estuary waters provide vital food resources for juvenile salmon as they pause to become acclimated to salt water before entering the Pacific Ocean. Bald eagles are present year-round; there are 30 to 35 active nest sites. Other fish species using the estuary include American shad, smelt, perch, starry flounder, bass, catfish, and Pacific lamprey. Harbor seals use sandbars and mud flats as resting sites at low tides, while seals and California sea lions feed on fish in the estuary. Beaver, raccoon, weasel, mink, muskrat, river otter, Columbian white-tailed deer and invasive nutria also live on the islands.

Harlows Creek is a stream in Wahkiakum County in the U.S. state of Washington. The name of the stream used to be Jim Crow Creek until it was changed by the U.S. Board of Geographic Names effective May 10, 2017 as part of an nationwide effort to remove offensive and/or derogatory names from geographic features. The new name commemorates John (1872-1953) and Mary (1888-1963) Harlow, who lived in the area during the 1870s. The origin of the name Jim Crow Creek was a reference to James D. Saules, a free black sailor who travelled widely throughout the Pacific in the 1800s. He was part of the United States Exploring Expedition. After the Cockstock incident along the lower Columbia River four nearby places where named "Jim Crow" due to Saules's involvement: Jim Crow Creek (Harlows Creek), Jim Crow Hill (now Beare Hill), Jim Crow Point (now Brookfield Point), and Jim Crow Sands. The incident also contributed to the Provisional Government of Oregon enacting the Oregon black exclusion laws. All three "Jim Crow" places names in Washington were renamed in 2017 due to the efforts of Washington Senator Pramila Jayapal. Jim Crow Sands, in the Columbia River, is in Oregon and has not been renamed as of 2023. Harlows Creek originates high on the slopes of Elk Mountain and flows south to the Columbia River, entering the river just east of the historical community of Brookfield, about 13 mi (21 km) east of Astoria, Oregon. Harlows Creek has one named tributary, Fink Creek. An early 20th century work suggested the point was named for crows that nested there. However, this reference also suggests a tree growing on the point could be seen far out at sea, an idea which should not be taken seriously due to distance as well as geographic features, so the reference itself might have little value.
