Hiking trail in Big Bend National Park

Hiked the six mile round trip from Big Bend National Park Rio Grande Campground to the hot springs.
It's right across the rio grande from Mexico.
This is me looking at some handmade items that some people from mexico left displayed for sale on a rock on the trail. They leave a jar for people to put money in. Then they sneak in later to get it.
It's illegal for us to buy the items.

Above is a view from the trail down to the rio grande and across Mexico.
