Join intrepid explorers and rangers as they investigate Florida's greatest mysteries.

Rangers think they may have located De Soto's fabled gold ship that sunk in Tampa Bay.

Zion National Park, Utah

With Halloween revelries occurring in and around Zion National Park over the next week, there will be an increased risk of accidents from drivers who have overindulged. Superintendent Jock Whitworth and Zion law enforcement rangers remind everyone to remain safe and sober while driving at this time of year. Nighttime is an especially dangerous time to be on the road, but Halloween night is often one of the deadliest nights of the year for impaired drivers.

To make this Halloween safe for everyone, make a plan before the festivities begin. Designate a sober driver, or call a sober friend or family member. Remember that Halloween falls on a Sunday this year, so many partygoers will be out on Friday and Saturday as well. If you happen to see a drunk driver on the road, don’t hesitate to contact local law enforcement. You can reach Zion National Park Emergency Law Enforcement Dispatch at (435) 772-3322.
