Cedar Mill

History

Before white settlement, the land was inhabited by the Atfalati, a subgroup of the Kalapuya, called the "Tualatin" or "Wapato Lake Indians" by settlers. Nearby Beaverton was known by the Natives as "Cha Kepi", meaning "Place of the Beaver". While in 1782 the native population exceeded several thousand, due to diseases brought by the settlers sixty years later, in 1842, the population was merely six hundred. By 1890, the members of the tribe had been reduced to 28 and the last known speaker of the Tualatin language, Louis Kenoyer, died in 1936.

Their son Joseph Murray sold the farm due to debts brought on by the Great Depression in 1936. According to Oregon Geographic Names, a "Cedar Mill" post office was established in 1874, in the John Quincy Adams Young House, built in 1869, which still stands on Cornell Road and is owned by the Tualatin Hills Park & Recreation District. The name was chosen by Young, who had "been commissioned to establish a post office in the area" and been…

Geography

According to the United States Census Bureau, the CDP has a total area of , all land. The appropriately named Cedar Mill Creek flows through the area. The creek begins its course in the Forest Heights neighborhood in northwest Multnomah County, then passes through Cedar Mill before flowing into Beaverton Creek in Tualatin Hills Nature Park. North Johnson Creek, another waterway in the area, begins south of Cedar Mill Creek and joins the main stream at the Nike World Campus. Cedar Mill Falls is the area's only waterfall, flowing near the Cedar Mill Greenway and JQA Young House. The waterfall, formerly used to provide power for the mill, is a 32-foot high basaltic rock formation. The Sue Conger Memorial Boardwalk, opened in June 2013, allows visitors of all abilities to view the falls. The only lake in the area is Hartung Lake, in the Hartung Farms neighborhood. Johnson Creek also flows through the area.
