This contribution analyses the first geological mapof Patagonia drawn by Darwin around 1840, and colour-painted by Darwin himself. It had remained unpublished and only a small version in black and white hadbeen printed before. The different units mapped by Darwin are analysed from amodern perspective, and his ability to show a synthesis of the complex geological structure of Patagonia is stressed.
