Q: Passage: James A. O'Neil built the county's first gristmill at the confluence of La Creole Creek (now Rickreall Creek) and O'Neils Creek over the winter of 18441845. The site was chosen for its proximity to water power for the mill, timber and a rock quarry that could provide millstones. The most important factor for siting the mill at this location, however, was its proximity to the Siskiyou Trail. A community formed around the mill as it was one of only two gristmills on the west side of the Willamette River at the time and it served settlers from as far away as northern Yamhill County and south as far as Linn and Benton counties. O'Neil offered lodging and a store for people who had made the long trip to his mill. Miners on their way to the California Gold Rush would also stop at the community for flour for the journey.
