Obsidian Flow

, La Pine, OR 97739
Obsidian Flow at Newberry National Volcanic Monument in Central Oregon


A four square mile area of black and grey volcanic glass where kids of all ages will enjoy one-mile interpretive walk. At just 1,300 years old, the Big Obsidian Flow is the youngest lava flow in Oregon.  Along the trail there are seven interpretive signs which discuss the geology, biology, history, and archaeology of the area. To get there, go 24 miles south of Bend on Hwy 97, then 15 miles east on County Road 21. It’s not far, but people who have visited call it “other worldly.”
