If you were to take a drive five to 10 minutes south of Bend Oregon you find the Central Oregon Lava lands. This is a great place to climb cinder buttes of old dried lava and explore caves! Yes.... lava caves. As you can see from the picture I posted to left, it is in the Deschutes National Forest. There you can also find a visitor's center and a lot of information about the area's history. A few miles North of the lava caves you can find the High Desert Museum, which is also a great source for information on Central Oregon's history and geology as well.
The other photograph is an image I took inside the Lava Lands, to left of the visitor's center. Highway 97 is the highway you use to access the Lava Lands and this sign shows visitors how to get back to the road. You can see there is access to the Deschutes River and Benham falls as well.
