The Best Time of Year to Hunt Each Location on the MoonShark Treasure Map

If you've explored the MoonShark Treasure Map, you already know there are incredible fossil hunting, shark tooth collecting, and seashell beachcombing spots all up and down the East Coast and Gulf Coast. But here's something most beginner hunters don't realize: timing matters. The same beach that yields buckets of shark teeth in winter might be completely picked over — or underwater — in the summer. Tides, seasons, storm patterns, and water levels all affect what washes up and when. Here's your seasonal guide to getting the most out of the best locations on the map.

Venice Beach, FL — Best in Winter & Spring (November through April)

Venice Beach — the Shark Tooth Capital of the World — is a year-round destination, but it really shines in the cooler months from November through April. Winter storms churn up sediment and push new fossils up from the ancient fossil beds just offshore. Lower tourist traffic means less competition on the beach, and the cooler temperatures make wading comfortable for extended hunts. Avoid peak summer months if you can — the beach gets crowded, and the pickings get thinner as the season's early hauls get scooped up.

Peace River, FL — Best in Dry Season (October through May)

The Peace River is one of Florida's most prolific fossil hunting rivers — a place where Megalodon teeth, horse teeth, mastodon bones, and ancient shells turn up regularly. The dry season from October through May is peak hunting time. Water levels drop significantly, exposing gravel bars and sediment beds that are submerged during rainy season. Lower, clearer water makes wading and sifting far easier. Summer and early fall bring Florida's rainy season — the river rises, current picks up, and visibility drops. Save Peace River for a dry-season trip.

Calvert Cliffs, MD — Best in Spring & Fall (April through June, September through November)

Calvert Cliffs in Maryland is one of the East Coast's premier fossil hunting destinations, where Miocene-era shark teeth and shells erode naturally out of the cliffs and wash onto the beach below. Spring and fall are the sweet spots — winter storms do the erosion work, and spring visitors get first access to the newly fallen material. Fall hunting is excellent as summer crowds thin out. Summer is hot, crowded, and the beach gets picked over early in the season. Always check conditions before visiting, as beach access can be affected by cliff erosion.

James River & York River, VA — Best After Rain Events (Year-Round)

Virginia's rivers are unlike most hunting locations — here, timing your visit after heavy rain events is more important than the season itself. Rain erodes the riverbanks and washes new material into the shallows, replenishing gravel bars with shark teeth, fossilized shells, and occasional arrowheads. The days and weeks following a significant rain event are prime hunting time year-round. Spring thaw and fall storms are particularly productive. Low tide always wins here — plan your arrival around the tide chart and go low.

Gulf Coast Beaches (Sanibel, Captiva, Fort Myers Beach) — Best in Winter (November through March)

Southwest Florida's Gulf Coast beaches are legendary for seashell collecting — Sanibel Island in particular is considered one of the top shelling beaches in the entire world. The secret is winter cold fronts. When a strong cold front pushes through from the north, it drives wind and waves onshore from the Gulf, pushing shells up onto the beach in massive quantities. The morning after a cold front passes is the single best time to shell on any Gulf Coast beach. Get there early — these conditions attract crowds fast.

Universal Rules for Any Location on the Map

Always hunt at low tide. This is the single biggest factor no matter where you are — low tide exposes more beach, more gravel bars, and more sediment that's normally underwater.

Hunt after storms. Rough weather churns up sediment and moves material around. The day after a storm is often your most productive day.

Go early. Not just for tides — every hour you're on the beach before the crowds gets there is another hour of undisturbed hunting.

Check local regulations. Some locations have rules about what you can collect and how much. Know before you go.
