State Route 139

This self-guided auto tour takes you through an area of "rocks that float and mountains of glass" and into one of the most unique geological regions in North America. The tour begins in the town of Tulelake and heads south on State Route 139. At CR97 head west and go into the town of Tionesta. Head another 12 miles west and you will come to Glass Mountain. The glass flow is from glassy dacite and rhyolitic obsidian that flowed from the same vent simultaneously without mixing. At nearby Medicine Lake you can camp, sightsee, swim, fish or take photos. Medicine Lake was once the center of a volcano. Native Americans believed that the lake had special healing powers. About 4.5 miles southeast of the lake is the Burnt Lava Flow. It is estimated to be about 200 years old which makes it the youngest lava flow in the area. The tour continues, but goes into the Lava Beds National Monument which only allows dogs in parking lots and along roads. In the national forest, which is the majority of this tour, dogs on leash are allowed on trails and in lake waters. Please clean up after your pets. For more information including maps, contact the Modoc National Forest office at 800 West 12th Street, Alturas, CA 96101, 530-233-5811.'s Sponsor's Sponsor
