That is the precise middle of California
The image is of the center of California. It shows a hexagonal stone slab half surrounded by a small stone wall. There is also a plaque on a taller rock next to the stone slab presumably telling you that you're at the center of California. This is all situated on a small dirt path that seems to be surrounded by scrub land. In the background there are some waist high scrub plants with small purple flowers and lots of grass on either side of the small dirty path.
