The name is the native name meaning at the foot of the mountain. The river begins about 12 miles east-south-east of Yachats, Oregon, in steep, thick forest, a half mile north of Klickitat Mountain and flows northward about three miles, joins Grass Creek then about 0.4 miles later joins with School Fork and turns westward. Keller Creek and Stump Creek join after about a mile of meandering, followed after a half mile by Neiglick Creek at river mile 10. The river bed widens significantly and levels out to become very slow moving and turns northward about a half mile, then westward at river mile 8. It meanders westward the rest of the way to the ocean. The sand and stone beach at the river bar is normally very shallow, which allows the tide to change the length of the river as much as a mile.
