Wavelength

Separated from Anchorage by 90 miles of rugged wilderness, BlockadeLake is a spot where few humans have ever set foot.The lakebed is accessible only by helicopter, and only in years when a glacial dam bursts and empties the lake in a way that leaves behind a safe place to land. The lake drains every few years, strewing massive icebergs across an eerie landscape that only a week before lay under hundreds of feet of water. I scouted for hours to find an ice formation that I thought would be safe to approach. Looking up through this ice cavern—with the bright summer sky luminescing different wavelengths through varying depths of ice—I knew I had found what I was looking for.
