Polar Plunge 2024

The annual Royal Canadian Geographical Society Polar Plunge is back!

This year we are joined by notable Canadians, adventurers, and RCGS Fellows. The #RCGSPolarPlunge will help the Society raise important funding for the rich storytelling and engaging interviews that take place under the banner of the Canadian Geographic Explore podcast.

Our goal is to raise $35,000! With your help we can continue to expand Canadians’ knowledge of our country’s diverse human and physical landscapes, better preparing them for an uncharted future.

Support the 2024 RCGS Polar Plunge!

Swimming with Shards (of Ice)

Saturday 17th Feb
I first began my polar plunges in Alaska in the late 1990s. Swimming in the glacial lakes in Soldotna and in the salmon-packed Kenai River felt amazing! The health benefits of cold-water swimming are well-documented, so it came to no-one's surprise that I swam in the sub-zero waters of Neko Harbour while working in Antarctica in 2008. The swim was documented as a post-credit scene for the film The Antarctica Challenge (2009). Other notable swims within the Arctic Circle include the Northwest Passage, Greenland, and Iceland. To see videos and pictures of these polar plunges, you can check out Google's map of "Mark Terry's Polar Plunges" here:
