Petroglyph Point
Lava Beds National Monument California
Several buttes of volcanic rock rise above the flatlands of the Tule Lake basin. Petroglyph Point is the largest and most dramatic. Ancient Indians carved petroglyphs into the soft tuff layers, high up because they were standing in canoes when lake level was higher than today
East of the bluff was the site of Tule Lake Segregation Center, one of the World War II Japanese relocation camps. Almost nothing remains, though a small museum has been created in the town of Tulelake. This is part of World War II Valor in the Pacific National Monument, headquartered at Pearl Harbor in Hawaii.
