The Willamette River, flowing through Oregon from the Cascade Mountains, joins the Columbia River.The State's Department of Geology and Mining (DOGAMI) recently released a lidar scan of the riverbed of the Villamet, revealing thousands of years of changes in the river's course.The image above shows a scanning range of about 50 feet from the bottom (white) to dark blue.The two direct currents to the left and right of the River into the Villamet are the Luckiamute and the Santiam.
