#GeorgesIsland is a #drumlin - rocks, gravel, sand and clay deposited by #glaciers as the last ice age ended 12,000 years ago. #NovaScotia has many drumlins including #CitadelHill and #OakIsland.

@AndyFillmoreHFX The word #drumlin comes from the #Gaelic word druim, meaning “rounded hill” or “mound.”

@AndyFillmoreHFX #GeorgesIsland was just a hill. #Halifax Harbour was mostly dry land after the last ice age - lakes and a stream that ran from the #SackvilleRiver to the sea. Georges became an island as rising seas filled the harbour, a process completed 5700 years ago.

We love TV show #TheCurseOfOakIsland which is about one of #NovaScotia's greatest mysteries! Here is a #geological take on the treasure hunt that highlights the searchers' challenge in figuring out what really happened on #OakIsland.

Like many islands in #MahoneBay, #NovaScotia, #OakIsland is a #drumlin - rock, sand, gravel and clay deposited by glaciers as the last ice age ended
about 12,000 years ago. Actually, the island is 4 connected drumlins.

Because #OakIsland is #drumlins, it may have layers of #gravel below sea
level which could explain the flood tunnel mystery. Searcher shafts might
just be intersecting sea water naturally flowing underground through porous gravel.
