Cerro Castillo in the evening light. Marble caves from Tranquilo the next morning. Gravel for a stretch, dust in the teeth. This is not Puerto Montt to O’Higgins — just the postcard.

Logging trucks and weather that changes in one valley. Capillas de Mármol in a small boat — the road only gets you to the shore.
