As noted in the previous post, this was a "hike" I took last August, during my mostly-annual trip to the Owens Valley. The BLM description and driving directions are here. I could have sworn I drove further along on US 6 before turning, to minimize my dirt driving. But I don't see on the satellite view where I would have turned.
In any event, there was a some dirt driving, but nothing my Camry couldn't handle. In any event, it's less than ten miles north of Bishop, and easy to get to.
The petroglyphs are on a volcanic outcropping. Several parking areas are nearby, along with (as I recall) some interpretive signs.
No shade in the area, so if you go in the summer, you'll want to go early or late, and bring something to drink, even though you won't be walking long.
I walked around the entire outcropping, and hit some of the cliff tops and pockets, just looking for petroglyphs. Most were pretty obvious, and I don't recall finding any hidden treasures. The petroglyphs were not as intricate as some I have seen.
If you see circular indentations in the face of the volcanic rock, they're not historic. Apparently, geologists drilled them to get samples to calculate the age of the rocks. Yes, seriously.
Undoubtedly under three miles to walk around the rocks, so this would not have made my original cut for a "hike," but it was something interesting I saw on a trip to the Owens Valley, and something I could share with my non-hiking wife.
Not a lot of plant or animal life visible in the immediate area. I saw a few lizards, and a few crows hung out on the rocks, until I got too close.
I think, technically, since it isn't a developed area, nor a national park or national monument, you can bring your dogs, though I'd likely want to keep them close, in the event that rattlesnakes are in the area. Didn't see any, but I'd be surprised if they weren't around. Volcanic rocks could be tough on their feet, too.
All in all, it was a nice little drive. Not big or dramatic enough to be a trip destination, but if you're already in Bishop and have an hour or so to kill, definitely worth your consideration.
