Hydrology
The park possesses a large drainage network, which consists of numerous rivers, streams, lakes, ponds and cascades that come from the Southern Patagonia Ice Field and flow towards the northeast until the Última Esperanza Sound that bathes the coasts of the city of Puerto Natales. The courses of water come from a longitudinal profile and are very turbulent with brusque changes in course, generated by waterfalls and rapids.
The Southern Patagonian Ice Field takes up the entire western side of the park. The Southern Patagonian Ice Field feeds four main glaciers; they are from north to south the glaciers: Dickson, Grey, Zapata and Tyndall. This last glacier is rapidly receding. The largest is Glacier Grey. It is divided into two arms, because of the appearance of a peninsula of ice, commonly called the Island or Nunatak, that becomes apparent a little more with each year that passes. The eastern arm measures about 1.2 km while the western has a width around 3.6 km. The longitude of the glacier in its path towards the interior of the park is 15 km.
Studies of the glaciers in the park have given scientists a clearer picture of the epochs of the earth, or what happened after the last glacial age.
