It's a wee bit cooler today but nothing like 126,000 years ago when the #AtlanticBubble was covered in ice!
The last ice age ended 10,000 years ago but there have been glacial periods in #NovaScotia on and off for at least 500,000 years...

During periods of climatic cooling, ice sheets develop and advance, aided by the reflection of the sun's light from the white snow surface. Sea levels drop as ocean water is used to make ice. The glaciers grow, coalesce and flow all the way out to...

...the edge of the continental shelf. There, melting and ice sheet disintegration begin as glaciers become buoyant in deep water. This starts the retreat process, which is accentuated as the sea-level rises, and helps to further destabilize the ice sheets.

#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.
