Brüggen Glacier Explained

Brüggen Glacier
Type:	Tidewater glacier
Location:	Chile
Coords:	-49.2167°N -74°W^[1]
Area:	1265km2
Length:	66km (41miles)
Terminus:	Sealevel
Status:	Advancing

Brüggen Glacier, also known as Pío XI Glacier, is in southern Chile and is the largest western outflow from the Southern Patagonian Ice Field. Now about 66km (41miles) in length, it is the longest glacier in the southern hemisphere outside Antarctica.^[2] Unlike most glaciers worldwide, it advanced significantly from 1945 to 1976, Brüggen surged 5km (03miles) across the Eyre Fjord, reaching the western shore by 1962 and cutting off Lake Greve from the sea. The glacier continued advancing both northward and southward in the fjord to near its present position before stabilizing. The growth covers a distance of more than 10km (10miles) north to south, adding nearly 60km2 of ice. The glacier is named after the German geologist Juan Brüggen Messtorff.

In the Karakoram Mountains, Siachen Glacier is 76 km long, Biafo Glacier is 67 km long, Baltoro is 63 km long, and Baltura is 57 km long. Kyrgyzstan's South Inylchek (Enylchek) Glacier is 60.5 km in length. None in the southern hemisphere outside of Antarctica and Bruggen Glacier approach this length.
