You’ve probably heard legends about planes and ships mysteriously disappearing in the Bermuda Triangle (or Devil’s Triangle): the area of ocean between Florida, Puerto Rico, and Bermuda. But those legends don’t come close to the very real, very serious disappearances that have plagued Alaska for decades. There’s a region of wilderness known by names like “Alaska’s Bermuda Triangle,” the “Bermuda Triangle of Alaska,” and the “Alaskan Triangle” — and no matter what name you give it, it’s far more deadly than its tropical cousin.
