Contributor used DJI Phantom 4 and Mavic Pro drones, combined with ground camera footage, to create this video of an epic helicopter ski trip to one of Europe's most famous glaciers. The Gorner Glacier runs down the west side of the Monte Rosa masif near Zermatt, Switzerland. With a surface area of nearly 60 square km (about 20 square mi.), it's the second largest glacier in the Alps. Monte Rosa, which is part of the Pennine Alps, is the second highest peak in the Alps after Mt. Blanc in France.
