The National Geographic Team recently completed a gruelling 6 week expedition to Southeast Greenland and celebrated with crew member Ethan Pringle sending it off a huge iceberg on an inflatable pizza.

The mission saw Mike Libecki climb the hardest route in the country up an unnamed mountain; a burly first ascent on uncharted terrain. On the long boat ride back to Tasiilaq, Ethan Pringle wasn’t done with “firsts” and decided to ride an inflatable pizza slice down a 300 foot iceberg, launching into the icy Arctic water below.
