Descripcion Geografica De Un Nuevo Camino De La Gran Cordillera,

This volume offers a rare glimpse into an 1837 expedition that sought a practical crossing of the great Andes to link the Argentine capital with Chilean ports. Commissioned by the viceroy of Buenos Aires, the author—an accomplished mathematician and astronomer—records his painstaking measurements, observations of the landscape, and the political obstacles that delayed the project for decades. The narrative situates the survey within the broader colonial ambition to unite two distant provinces under a single authority.

The work is organized as a collection of diaries, official correspondence, and detailed itineraries that trace the route from San Agustín de Talca through the foothills, across the Río Claro, and toward the Pacific coast. Along the way, the author describes rivers, marshes, and the fertile fields of Maule, while noting the presence of local indigenous groups whose raids threatened the nascent trade corridor. Though the manuscript is dense with precise distances and topographical minutiae, it paints a vivid picture of the rugged terrain and the hope of turning a remote mountain pass into a vital commercial artery.
