Sure, we could’ve found stock images of Camp Muir for Allison Williams’s essay (“Meet Rainier's Temporary Town at 10,000 Feet”). But would stock really tell this story? No. So I set about finding a photographer who could both make the grueling trek and create the images we needed. For some this is a dream assignment, for others it’s quite literally a pain. Thankfully only the former was true for landscape and adventure photographer Mac Holt. He survived his first (though, certainly not his last) trip to Muir mostly unscathed, save some elevation-induced eyestrain with help from our intrepid senior editor, who showed him the way and carried his gear for part of the trip. I hope you’ll agree the result is, well, breathtaking.
