On 3/5/2022, while I was in Texas I went to the Seminole Canyon State Park. In this park you can see Pecos River rock art dated back to 4,000 years old. It is considered to be some of North America’s oldest pictographs. You can hike down to the canyon where you can see it.
They have guided tours you can take to the art in the caves. There are bicycle trails, hiking and camping.
There is a museum that you can look at the talks about everything. Very interesting. Here some things to see in the museum.
Here is some pictures of what you can see around the state park.
