Our first night in Joshua Tree NP is at the Jumbo Rocks Campground. The campground is mostly for tent campers, and the few spots that can actually accommodate us are pull-offs that are just wide enough to fit an RV. Skull Rock is a short hike/scramble from the campground, but this unusual rock is more easily accessed from the main road.
When we arrive, there is a man with his body pressed against the rock, talking to it like it is a dead relative.
From either side, the rock looks like a skull, but look at it head-on, it doesn't look like anything.
What is more fun is climbing around on the piles of perfectly-sized boulders all around the campground.
A grey and red plant grows at the bases of some of the rocks:
