These shots are from Picture Rock Pass in central Oregon, named for the boulder with petroglyphs right beside the old wagon road over the pass. There are numerous petroglyphs and other Clovis period aritfacts in this area. In many places the ground is littered with obsidian chips from arrowhead knapping, but they might be from more recent Paiute inhabitants. None of the sites are marked to discourage vandalism. Just wandering around in the area turns up many interesting finds.
Wikipedia states: “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.” https://en.wikipedia.org/wiki/Picture_Rock_Pass_Petroglyphs_Site
The last shot is the old wagon road that crosses the modern highway at the summit of the pass.
