Picture Rock Pass Petroglyphs Site
The Picture Rock Pass Petroglyphs Site is in northern Lake County, Oregon, United States. The site is located near the summit of Picture Rock Pass on land administered by the Bureau of Land Management. The designs were scraped into a basalt boulder by ancient Native Americans, probably between 7,500 and 12,000 years ago. No one knows the meaning of the petroglyph designs. Because of its unique archaeological and cultural significance, the Picture Rock Pass Petroglyph Site was listed on the National Register of Historic Places in 1975.
The Picture Rock Pass petroglyphs are carved on a south-facing basalt boulder near the summit of the pass. No one knows when the Picture Rock Pass petroglyphs were created or who carved them. However, they were probably created during either Clovis Period (10,000 and 12,000 years ago) or the Stemmed Point Period that followed (7,500 to 10,000 years ago), placing the likely period of the rock carvings sometime between 7,500 and 12,000 years ago.
