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 great blue heron (ardea herodias) is a large wading bird commonly seen in the rivers and marshes of Florida and other parts of North America. They are most often seen stalking the shallows in search of prey (mostly small fish). It is distinctive for its size (the largest heron in North America and one of the largest in the world), in-flight silhoutte, and blue-gray coloration as an adult. The call of the great blue heron is described as a harsh croaking sound; between the sound and size, a low flying heron might cause the unwary to think they are under attack by a pterodactyl.
