Incredible world's first windsurfer to travel down snowy mountain

Swapping the sea for the snow, one extreme windsurfer decided to sail at high speeds down a 5,656 foot mountain.
Levi Siver, 36, who fell in love with the ocean as a child in Maui, took to the peaks of Mount Rishiri in Hokkaido, Japan, to pull off the daredevil stunt.
Video footage shows the medal-winning sportsman in action, as he skilfully surfs down slopes of fresh powder.
There are moments when he flies into the air as he tackles mounds of compact snow.
According to Red Bull - who Siver represents as a professional athlete - the stunt marked a world first.
The American came up with the idea five years ago and spent months prepping for the adrenaline-pumping descent.
Siver used a specially adapted rig with a modified finned base.
There were no bindings on the board and Siver wore surf boots instead of sturdier snow gear.
Although footage of him looks flawless, it wasn't all plain sailing. It took 20 days of filming to get the footage required during the month of March.
Before whizzing down the slopes, he had to complete a two-hour hike battling lows of -13 degrees Celsius.
The weather was also very temperamental and Siver often had to wait several hours in a bid to catch the perfect winds.
His camera crew would then catch him in action.
Describing how it felt to windsurf on the snow, Siver said: 'On the drop in you get the same feeling as when you’re windsurfing. But you’re looking down on a mountain, not the ocean. I got this exhilarating feeling that I can’t even really describe.
'The strongest wind I caught was about 9.3mph.'
Siver was born in Idaho, near the snowy slopes of Sun Valley, and as a child he took to skiing and snowboarding.
But after moving to the shores of Maui, Hawaii, at the age of 11, Siver’s future calling as a professional windsurfer was sealed.
He said his most recent endeavour came about after deciding to marry his two favourite sports, snowboarding and windsurfing.
He concluded: 'The idea for this project stemmed from the vision that we could transfer the elements of windsurfing onto a mountain and create the same exhilarating experience the surfer gets on the water.
'I’m always trying to find ways to challenge myself, but this project really sparked my curiosity.
'I wanted to be the first person to try alpine windsurfing on a finned board.'
