The Gray Glacier ( Spanish Glaciar Gray ) is a glacier in Chile .
location
The glacier is located in the southern Andes in the province of Última Esperanza of the Chilean Región de Magallanes y de la Antártica Chilena in the northwest of the Torres del Paine National Park , about 150 kilometers northwest of the city of Puerto Natales .
description
The Gray Glacier is an outlet glacier of the Campo de Hielo Patagónico Sur (Southern Patagonian Ice Field), the largest ice cap in the southern hemisphere outside of Antarctica . It stretches from this ice field to the southeast and calves with three separate glacier tongues into Lago Gray , a lake at the edge of the glacier . The outflow of Lake Gray, the Río Gray , is a tributary of the Río Serrano , which flows into the Pacific fjord Seno Última Esperanza .
When surveyed in 1996, the glacier was 28 kilometers long and had a total area of 270 square kilometers. At its end, before being divided into three tongues, the glacier is about 6 kilometers wide and about 30 meters high.
Comparisons of satellite images from NASA show that the glacier tongue has receded several hundred meters over the past few decades. At the end of 2017, a sheet of ice 350 meters long and 380 meters wide broke off from the top of the glacier.
