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 eastern meadowlark (Sturnella magna) is a medium-sized icterid bird found from eastern North America to northern South America. Meadowmarks have a distinct appearance: white with lots of dark streaks, a yellow belly and throat, and a black V on the breast. They feed mostly on anthropods. The eastern meadowlark's song has been described as "melancholy whistles" and their song is the best way to tell eastern and western meadowlarks apart, although there are some minor differences in appearance as well.
