One of the less known parts of DuPuis is the Powerline Grade along the eastern perimeter. A one way trip is 13 miles long and can be traveled on foot, bike, horse, or car. As the name implies, the shellrock road parallels high tension power lines running south from the FPL Indiantown plant. The southern half of the road runs between a canal (with many resident alligators) and the adjacent Corbett WMA. You may also see otters, deer, birds and various Florida fauna. Bringing your camera is recommended. Happy caching!

The river cooter (Pseudemys concinna) is a freshwater turtle native to the central and southeastern United States. It is commonly seen in Florida lakes, rivers, and marshes sunning itself on logs or rocks. Cooters mostly eat aquatic plants and small animals like fish. They are unable to swallow food out of the water and also sleep underwater.
