The water is calm, there’s no cloud in the sky, and the pizza slice is inflated. If not for Ethan Pringle, dressed just in his underwear and holding a slice of pizza, this iceberg in Greenland would be an idyllic and tranquil location.

Ethan Pringle, a professional rock climber, has experienced his fair share of adventure, but nothing like this. As we see in the video he posted on his Instagram, he partially scales the iceberg, lets out a whoop and then hurls himself down hundreds of feet down this massive iceberg. The frigid water 20 feet below the edge breaks his fall.

Pringle says that whizzing down an iceberg is “the coolest thing I’ve probably ever done.” He commented to all his Instagram followers: I must interrupt my regularly scheduled broadcasting to show you a clip of the coolest thing I’ve probably ever done: ride an inflatable slice of pizza down a massive iceberg. When I first learned @mikelibecki brought an inflatable pizza to Greenland to float down the river on, I knew I wouldn’t be able to leave the country with my head held high unless I sacked up and rode the thing off a berg. On our second to last day on the boat headed back to civilization we came across the perfect iceberg- a big ole mother with a long, perfectly angled slope that led to a 20 foot drop off. Well I’m here to tell you folks, pizzas can fly and dreams do come true. Thanks for capturing this unforgettable moment @ladzinski, @andy_mann and @connor_seybert, and thanks for always believing in and supporting my dreams @mikelibecki. You are true friends!

Pringle arrived in Greenland with National Geographic, as part of a six-week expedition. Pringle came to conquer, “the hardest route in the country up an unnamed mountain” along with his climbing partners.

As Pringle mentioned on his Facebook page, this was,  “unchartered terrain. I knew I wouldn’t be able to leave the country with my head held high unless I … rode the thing off a berg.” We’re so glad he did!
