There are spines. And then there are Haines, AK spines. 

Parkin Costain’s compilation of spine shredding from last season puts it all into perspective. Last spring, Costain spent a few weeks up north filming at SEABA Heli with Teton Gravity Research. The trip culminated in a first descent of a line Costain had been looking at since he first skied with SEABA almost 10 years ago, the legendary Mono Spine.
