Everyone loves a treasure hunt…

Nearly 90 years ago Bradford Washburn and Robert Bates abandoned a gear cache remote in the Yukon in their attempt to make the first ascent of Mount Lucania.

“What it grieved Brad most to leave behind was his large-format Fairchild F-8 aerial camera, which exposed five-by-seven-inch negatives, the first of a series of heavy and expensive apparatuses with which Washburn would capture his matchless aerial images of the mountains of Alaska and the Yukon,” wrote David Roberts in his 2002 book, Escape from Lucania.

While no climbing party had ever reported finding it, most people speculated that the cache had fallen into one of the numerous crevasses on the Walsh Glacier.

But what if it didn’t?
