Picture Rock is between Summer and Silver Lakes in the Oregon Outback.
The petroglyphs were left on this boulder were most likely created during either the Clovis Period (10,000 and 12,000 years ago) or the Stemmed Point Period (7,500 to 10,000 years ago).
The rock wasn’t easy to find. In fact, without Google Maps, I doubt we would have. That’s a good thing, though. The harder it is to find, the more likely it is to be preserved. But it was worth the hunt.
I found this diagram on Wikipedia, which shows the carvings in clearer detail.
Four arms? And, two of the figures have horns. It’s obviously either an alien or yeti attack, and the one dude is escaping on horseback. What do you think it means?
