The origin of valleys crossing patagonia and their relation with cordilleran uplift
The infinite Patagonian steppe, its fluvial network and patterns of fiords and lakes is full of amazing uniqueness, their mere existence and beauty wake up our need of discovering their natural causes. This task requires to have been lost in the neverending Patagonia, to hold all of its infinite det...

A capricious terrain characterize Patagonia, where some of the mountain valleys are below the level of extra-Andean Mesetas, and the northern lakes located in the eastern foothills drain towards the Pacific Ocean. The Southernmost Andes are affected by strong glacial erosion and traverse by the Magellan Strait and the Beagle Channel, allowing to navigate connecting both the Atlantic and Pacific oceans. The Andean rivers of Patagonia have to dodge the Somoncurá and Deseado massifs along the “codo del río Senguer”, a morphic feature inherited from Gondwana times, and shaped during the late Cenozoic. This history was evident for Groeber, who expressed the importance of rivers and glacial carving the Cordillera, a discussion that still is motive of debate, almost 100 years later. © 2017, Asociacion Geologica Argentina.
