This should be an easy find. 
All the spots are in city limits. The listed coordinates are bogus.
You will not have to look hard to find these statues. They can be seen from these spots. Please, no cheating using maps. Go to the sites and enjoy the art.
Parking is available nearby, please park legally. Muggle activity can be high so be stealthy.
At the final spot, approach from the south to avoid multiple muggles. This will allow you to enjoy the little garden and labyrinth too. I believe all spots are wheelchair accessible.

Statues information
The downtown sculptures project is part of the Business Improvement District of downtown which was created to make improvements in a given area. The district wanted to put in more visual interest, to elevate downtown. The purpose was to create a special destination, a cool, fun place, an inviting place for people to be, not just for the citizens of Stillwater, but anybody visiting. The statues were cast by Bronzeman, a foundry in Oak Park, Calif.

The Angie Debo Statue sculpted by Phyllis Mantick.
Dr. Debo was selected as the subject of the sculpture due to her international recognition for books on Oklahoma's Native Americans, her work at the OSU Library, her home in nearby Marshall, her portrait recognition at the State Capitol and no known sculpture of Debo anywhere else in the nation. She was primarily a researcher and writer of books on the Five Civilized Tribes, Geronimo, and the history of Native Americans and of Oklahoma. Surrounding the base of the statue are seals of the 38 federally recognized Oklahoma Native American tribes.

Labyrinth
This is a five-circuit labyrinth (peace path). A labyrinth is a single path that guarantees you will get to the center. It allows you to calm down and soothe your spirit, to move into a place of introspection. A labyrinth guarantees success and there is no wrong way to go. It helps us recognize that the journey is as important as reaching the goal. The sunken prayer garden is landscaped and has a peace pole on the southeast corner. A bench is at the very center of the path.
