The Wright Valley is the largest area of the three Antarctic dry valleys, which lie on the western coast of McMurdo Sound over the Ross Island.

Geography

The valley is situated between the mountain ranges of Olympus and Asgard Range Range, and is about 60 km long and an average of 8 km wide. The Vandasee is in it, as well as 9 km to the west of the small Don Juan lake, the waters with the highest salt content of the soil. The valley is the longest Antarctic river, the Onyx River, flowing through it. West direction bifurcates the valley in North Fork and South Fork (where the Don - Juan- lake lies ) about the Dais, in order to unite the Upper Wright Glacier in an area that is known as Labyrinth, again. At the eastern end of the valley, towards the coast, lies the Lower Wright Glacier, Brownworthsee lies on its western end. In the eastern half of the valley flow from the south, from the Asgard Range, several glaciers in the valley: the Meserve Glacier, the Newall Glacier and the Albrich Glacier, just to name a few.

Climate

In the Antarctic winter (April to October), the temperatures drop to minus 70 ° C in summer (November to March), they rarely reach the freezing point. At the former New Zealand Vanda Station on the same lake, however, the highest ever measured in the Antarctic temperature has been reached on January 5, 1974 15.0 ° C. The ever- prevailing wind escapes the valley the last moisture, so it is with the other two valleys, the driest area in the world. It is estimated that there were already several million years no more precipitation.
