This is the introduction of a very interesting state park in Florida.  The mounds have mostly been preserved and now are as part of this park.

The main or religious mound.

We climbed the steps to the top of this mound.  The view from here is spectacular.

A stele is an ancient marker stone.

According to the plaque, a face is carved on the opposite side.

Do you see the face?

This is a close-up of the "face".
