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 Florida box turtle (Terrapene carolina bauri) is a subspecies of turtle native to Florida. Box turtles have domed shell with a hinged plastron that allows it to close its shell tightly. Florida box turtles are distinctive for the radiating yellow stripes on their shells. They are most commonly found in/near swamps, marshes, or other wetlands but rarely enter water deep enough to require swimming. Their diet consists of various insects, worms, plants, and fungi. They are often kept as pets.
