The scarcity and spaciousness of Central Oregon's Lava Lands create an area of striking beauty both above and below ground. Large areas are covered by lava flows. These rivers of rock consist of basalt which is a molten lava that spreads quickly and sometimes flowed up to 70 miles. Great tunnels wind through many of these flows and suggest that awesome forces of nature were once at work. These ancient lava tunnels (called tubes) are one of the area's most interesting secrets.
