About five miles down Woodenshoe Canyon, in southeast Utah’s Dark Canyon Wilderness, David stops on the trail ahead of me and points to a barely distinguishable feature in the cliffs above us. We drop our backpacks and follow a faint path in the sand and up onto sandstone slabs, scrambling and zigzagging our way up onto a wide ledge below an overhanging cliff face. In the shaded alcove below that overhang, we stop before the ruins of a tiny, one-room stone structure perhaps large enough for two people to lie down inside, built centuries before Columbus arrived in the New World.
