An Alaskan outdoor educator and his wife showed off the beauty of a once-in-a-decade 'ice window' as they glided along a translucent, solid lake thanks to the rare weather event.

Luc Mehl, an Alaska native, author and outdoor educator with certifications in swift water and ice rescue instruction, took the skate with his wife, Sarah Mehl Himstad, in late October.

They were able to hit the ice on Rabbit Lake near Anchorage in late October due to what's known as an 'ice window.'

The lake froze over, as the region often does, but an unusually cold and dry season created an almost translucent effect, allowing people to skate and stare down into the depths of the lake. 

Mehl and Himstad shot footage of themselves and others skating over the clear lake from October 23 to 26, cruising over massive rocks and other aquatic life.
