The 0.4-mile Trail of the Whispering Pines winds its way through the forest near the visitor center. You get great views of pine trees, Lava Butte, and several nearby volcanoes. This path sits on part of Newberry Volcano, a 1,200-square mile shield volcano.
South Sister, pictured on the left above, is the youngest and most geologically active of the Three Sisters volcanoes. The mountain last erupted 2,000 years ago, but a “bulge” began forming in 1997. By 2001, the bulge grew to 9 inches in height and 10 miles in diameter. Its growth since that time has slowed considerably. Both South Sister and Newberry are regularly monitored for volcanic activity.
You can get to top of the Lava Butte cinder cone by hopping onto a shuttle or taking a short hike from its base. The 500-foot tall butte is located at the Lava Lands Visitor Center in the Newberry National Volcanic Monument about eight miles south of Bend, Oregon. Lava Butte is one of the hundreds of cinder cones in the immediate area.
Lava Butte erupted about 7,000 years ago. There are several trails that wind through the ancient lava flows and onto the flanks of the butte. There were three main gutters where most of the lava flowed. Ten square miles of pine forest were buried by lava. The lava flows blocked the Deschutes River in five places. If you walk the trail to Benham Falls you can see where the river has made its way through the lava rock.Continue reading
