SOMETIMES ALL IT TAKES is showing up. This occurred to me during the hike into the confluence of Rios Azul and Blanco near El Bolsón, Patagonia, pausing for a moment to rest the knees and study the terrain–the two rivers dropping out of steep notches in the cordillera, then joining in the valley where I could hear whitewater hundreds of meters below.
