 A well-known free African-American named George Washington Bush entered the state of Washington through Parker's Landing, and eventually traveled to the center of the state, where he founded the community of Tumwater.David C. Parker came out on a wagon train with Bush and both floated down the Columbia on rafts in 1845.In 1846, when the Oregon Territory land dispute was resolved between England and the United States and the northern boundary was moved to the 49th parallel, Parker was quick to file for a land grant, which included the popular beach landing that would later assume his name and become the marina for the Port of Camas-Washougal.
