Blanco through the narrow canyon of Salto del Soldado. We had a pushy 1,500 cfs, lots of scouting, and a portage around a small dam near km 4. Gradient in this 8 km stretch is 25 mpk. The absolute crux of this run, one of the most severe in Chile, is the Salto del Soldado.
Legend has it a soldier jumped the narrowest point of the walls on horseback.
Check this run out with care.
