The Clackamas County Historical Society's Clackamas County Historical, 1966-1967: History of Willamette Falls provides a detailed chronicle of the monumental waterfall situated along the Willamette River in northwestern Oregon. The narrative centers on the dramatic basalt horseshoe of the falls, mapping how this vital geographical chokepoint spurred the development of pioneer settlements like Oregon City and West Linn on opposing riverbanks. By documenting early industrial power generation, indigenous fishing encampments, and the construction of navigational locks, the text highlights the falls as a crucial artery connecting the fertile Willamette Valley to the broader Columbia River basin. Ultimately, this historical account vividly captures the profound physical and economic impact of this specific aquatic landmark on the early expansion of the Oregon Territory.
