Humboldt Mountains (Antarctica)
The Humboldt Mountains are a group of mountains immediately west of the Petermann Ranges, forming the westernmost portion of the Wohlthat Mountains in Queen Maud Land, Antarctica.

Queen Maud Land
Queen Maud Land ( no, Dronning Maud Land) is a roughly region of Antarctica claimed by Norway as a dependent territory. It borders the claimed British Antarctic Territory 20° west and the Australian Antarctic Territory 45° east. In addition, a small unclaimed area from 1939 was annexed in June 2015. Positioned in East Antarctica, it makes out about one-fifth of the continent, and is named after the Norwegian queen Maud of Wales (1869–1938). In 1930, the Norwegian Hjalmar Riiser-Larsen was the first person known to have set foot in the territory. On 14 January 1939, the territory was claimed by Norway. On 23 June 1961, Queen Maud Land became part of the Antarctic Treaty System, making it a demilitarised zone. It is one of two Antarctic claims made by Norway, the other being Peter I Island. They are administered by the Polar Affairs Department of the Norwegian Ministry of Justice and Public Security in Oslo. Most of the territory is covered by the east Antarctic ic ...

German Antarctic Expedition (1938–1939)
The German Antarctic Expedition (1938–1939), led by German Navy captain Alfred Ritscher (1879–1963), was the third official Antarctic expedition of the German Reich, by order of the "Commissioner for the Four-Year Plan" Hermann Göring. Councilor of state Helmuth Wohlthat was mandated with planning and preparation. The expedition's main objective was of economic nature, in particular the establishment of a whaling station and the acquisition of fishing grounds for a German whaling fleet in order to reduce the Reich's dependence on the import of industrial oils, fats and dietary fats. Preparations took place under strict secrecy as the enterprise was also tasked to make a feasibility assessment for a future occupation of Antarctic territory in the region between 20 ° West and 20 ° East. Preparations In July 1938, Captain Alfred Ritscher received a mandate to launch preparations for an Antarctic expedition and within a few months he managed to bring about logistics, equip ...

Paris Commune
The Paris Commune (french: Commune de Paris, ) was a revolutionary government that seized power in Paris, the capital of France, from 18 March to 28 May 1871. During the Franco-Prussian War of 1870–71, the French National Guard had defended Paris, and working-class radicalism grew among its soldiers. Following the establishment of the Third Republic in September 1870 (under French chief executive Adolphe Thiers from February 1871) and the complete defeat of the French Army by the Germans by March 1871, soldiers of the National Guard seized control of the city on March 18. They killed two French army generals and refused to accept the authority of the Third Republic, instead attempting to establish an independent government. The Commune governed Paris for two months, establishing policies that tended toward a progressive, anti-religious system of social democracy, including the separation of church and state, self-policing, the remission of rent, the abolition of child l ...

Valleys Of Queen Maud Land
A valley is an elongated low area often running between hills or mountains, which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In areas of limestone bedrock, dry valleys may also result from drainage now taking place underground rather than at the surface. Rift valleys arise principally from earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms that may be global in use or else applied only locally. For ...
