An hour south of Anchorage Alaska is a fjord called Turnagain Arm. At this place of exceptional beauty the incoming tide collides with water draining out of the fjord and creates a tidal bore. The video shows three standup paddle-boarders cruising up the fjord.

A group of Stand Up Paddle Surfers rode the bore tide along the Turnagain Arm near the Seward Highway on Friday September 10, 2010 with the Kenai Mountains in the background.
