On January 12, 2026, beachgoers at Pepper Park in Fort Pierce witnessed a scene straight out of a history book—literally. After a local scuba diver discovered a WWII-era mortar in the shallow surf, the St. Lucie County Sheriff’s Office Bomb Squad was forced to conduct a controlled detonation, sending a massive plume of sand and seawater into the Florida sky.

While it felt like a freak occurrence, for long-time Treasure Coast residents, it was a reminder of our city’s vital role in global history. Our pristine beaches were once the “proving grounds” for the most dangerous missions of World War II.

🎖️ The “Birthplace of the Navy SEALs”

From 1943 to 1946, Fort Pierce was home to the Naval Amphibious Training Base (NATB).<!–> This was no small outpost; it was a massive 19,280-acre military reservation that stretched 25 miles from Vero Beach to Jensen Beach, encompassing both North and South Hutchinson Islands.–>

  • The Mission: Over 140,000 personnel passed through Fort Pierce to train for the D-Day invasion of Normandy and the island-hopping campaigns in the Pacific.–>

    <!–>

  • The Units: This was the primary training site for the Naval Underwater Demolition Teams (UDT)—the legendary “Frogmen” who were the direct precursors to today’s Navy SEALs.–>

  • Dynamite Point: If you’ve ever wondered why the tip of Fort Pierce Inlet State Park is called “Dynamite Point,” it’s because UDT teams used that exact spot to practice blowing up beach fortifications with high explosives.–>

🌪️ Why is this happening in 2026?

If the war ended in 1945, why are we still finding “live” rounds 81 years later?

  1. The 2026 Storm Surge: Following the significant cold fronts and erosion events of early January 2026, several feet of sand were stripped from the coastline. This natural “excavation” uncovers items that have been buried deep for decades.

  2. Dredging Operations: Ongoing beach renourishment and dredging projects often stir up the seabed, pulling old military markers and mortars from the offshore limestone reefs where they’ve been lodged.

  3. Iron-Clad Durability: Military ordnance from this era was designed to withstand harsh conditions. While many items are heavily encrusted in barnacles (looking more like rocks than bombs), the internal explosives can remain volatile for over a century.

📋 The “3-R” Safety Rule for Beachgoers

If you are beachcombing near Pepper Park, Avalon State Park, or Navy Sands and spot something metallic or unusual, follow the U.S. Army Corps of Engineers’ guidelines:

  • Recognize: WWII ordnance rarely looks like a “cartoon bomb.” It often looks like a rusty pipe, a heavy metal cylinder, or a barnacle-covered rock. If it looks man-made and old, assume it’s dangerous.

  • Retreat: Do not touch, move, or kick the object. Even after 80 years, these items can be sensitive to movement or changes in pressure.

  • Report: Call 911 immediately. The St. Lucie County Bomb Squad and military EOD (Explosive Ordnance Disposal) teams are highly trained to handle these specific local finds.

🎯 Conclusion: A Legacy Beneath the Sand

Living on the Treasure Coast means sharing our backyard with the ghosts of the Greatest Generation. While the January 2026 detonation was a startling event, it serves as a powerful tribute to the grueling training that happened right here on Hutchinson Island to secure the freedoms we enjoy today.

The next time you’re walking the shore at sunset, remember: those dunes didn’t just protect us from the ocean—they helped win a war.
