Paleocene unicorn. The Aquia Formation here yields ~60 million year old shark teeth - vastly older than Calvert. Striatolamia striata and goblin shark cousins.
Workable but not ideal. Best window opens around the 1:31 PM low (0.3 ft). Light N winds (4 mph) — calm surface, easy spotting. Spring tide cycle adds a little extra range.
Next 3 days: Next few days look steady — all good-range. Pick whatever fits your schedule.
Plan around the fair low-tide window. Cliff site — continuous erosion baseline · low tide during daylight · spring tide · best low 53.
Impact on visibility and stir-up over the next 5 days.
Cliff sites score from a baseline plus recent storm stir, daylight low tide timing, wind exposure, and seasonal events (only when storms are actually shedding cliff material).
Fair. Standard conditions — go for the volume hunt.
We are deliberate about which factors to include. These are not currently in the model:
If you think we should add one of these, log a hunt with notes — every rated outcome helps us decide which signals actually predict tooth count.
Late winter freeze-thaw cycles destabilize the Chesapeake Group cliffs. March–early May historically produces the most fresh fall material on the beaches at Brownie's, Matoaka, and Westmoreland.
Walk the Potomac shoreline at very low tide. Most finds are small but ancient.
MD state park: surface beach collecting allowed.
Trophy = headline find · Rare = real score · Uncommon = some trips · Common = most trips.
The beachcomber's bonus round — what else the geology gives up.
