Yoncalla Falls is a 35-foot waterfall on Yoncalla Creek in Yamhill County, Oregon, in the Coast Range region. It lies about 7.3 miles north of Grand Ronde and roughly 33.8 miles northwest of Salem as the crow flies.
At 35 feet it is on the modest side for Oregon, where the typical waterfall with a recorded height stands around 54 feet; it ranks 282nd of 425. By form it is a horsetail, where the water keeps some contact with the bedrock as it falls.
The Coast Range is a belt of steep, deeply dissected hills along the Pacific, wrapped in dense temperate rainforest of Douglas fir, western hemlock, Sitka spruce and red alder. Heavy winter rain feeds short, fast creeks lined with ferns, salmonberry and moss that drop steeply toward the ocean or the Columbia.
