It's harder than it looks to see the whole of Sky Rock. It's on a relatively flat rock, facing up toward the sky (hence the name), rather than on a vertical wall, as most petroglyphs are, so it's impossible to see from below. It's also large, easily over 20 x 20 feet. It's carved on a very large rock, which is perched against another vertical rock below it, forming a sort of cave/tunnel below it.

Especially challenging is that you cannot climb on the petroglyph rock itself, in order to protect it. The only way is to climb on a large rock above it, which I'm sure younger, more agile folks can manage, but I barely made it. The location is undisclosed, so you sort of have to know someone who's been there in order to find it. I can say it's located on the volcanic tablelands near Bishop, California. Hope you enjoy the ancient art. Cheers.
