Stockyard Rock

Out in Death Valley, there is a rock a friend told me about a long, long time ago. I'd been wanting to visit it for some time but never stopped to check it out. So, in early 2021 I finally did.
What's so special about this rock in Death Valley? It has a mysterious historical inscription on it. It basically reads: "Well, this looks like the stockyard." There might be a bit more but I'm not sure.
What is equally odd is there doesn't seem to have been a corral or enclosure here. The rock overlooks a broad wash. There is a bit of mining activity nearby but I don't know why this rock is here. There are no other carvings nearby.
Another mystery of Death Valley.
