Teasing out the history of a place celebrated for timelessness—where countless paddle strokes have disappeared into clear waters—requires a sure and attentive hand. Stephen Wilbers's account reaches back to the glaciers that first carved out the Boundary Waters and to the original inhabitants, as well as to generations of wilderness explorers, both past and present. He does so without losing the personal relationship built through a lifetime of pilgrimages (anchored by almost three decades of trips with his father). This story captures the untold broader narrative of the region, as well as a thousand different details sure to be recognized by fellow pilgrims, like the grinding rhythm of a long portage or the loon call that slips into that last moment before sleep.
