This place is a HUGE lava flow (extinct) that covers thousands of acres of land in eastern Oregon. It is about an hour of the main road on gravel roads that are in good shape. It is beautiful and mysterious. It is easy to spend several hours here looking at all the amazing lava structures left behind from thousands of years ago when this lava erupted and engulfed this area. There are obvious vents to see where a lot of lava blew up out of the ground. Coffee Pot Crater is an amazing blend of colors and rock types. The road by the same name ends right at the crater and there is a small display/sign that describes the history and features. There are some small lava tube caves you can go into where the hot lava retreated leaving empty space. Evidence of lava rivers and flows are everywhere.
