Through Antarctica, Oslo and India

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 ice sheet, and a tall ice wall stretches throughout its coast. In some areas farther within the ice sheet, mountain ranges breach through the ice, allowing for birds to breed and the growth of a limited flora. The region is divided into, from west to east, the Princess Martha Coast, Princess Astrid Coast, Princess Ragnhild Coast, Prince Harald Coast and Prince Olav Coast:

The waters off the coast are called the King Haakon VII Sea.

There is no permanent population, although there are 12 active research stations housing a maximum of around 40 scientists, the numbers fluctuating depending on the season. Six are occupied year-round, while the remainder are seasonal summer stations. The main aerodromes for intercontinental flights, corresponding with Cape Town, South Africa, are Troll Airfield, near the Norwegian Troll research station, and a runway at the Russian Novolazarevskaya Station.

Geography

Queen Maud Land extends from the boundary with Coats Land in the west to the boundary with Enderby Land in the east, and is divided into the Princess Martha Coast, Princess Astrid Coast, Princess Ragnhild Coast, Prince Harald Coast and Prince Olav Coast. The territory is estimated to cover around 2,700,000 square kilometres (1,000,000 sq mi), which roughly corresponds to the sizes of India, Argentina or Kazakhstan. The limits of the claim, put forth in 1939, did not fix the northern and southern limits other than as "the mainland beach in Antarctica ... with the land that lies beyond this beach and the sea beyond". The sea that extends off the coast between the longitudinal limits of Queen Maud Land is generally called King Haakon VII Sea.

There is very limited ice-free land at the coast, in the vicinity of Japan's Showa station. The remainder of the coast consists of a 20-to-30-metre high (70 to 100 ft) wall of ice almost throughout the entire territory. It is thus only possible to disembark from a ship in a few places. Some 150 to 200 kilometres (90 to 120 mi) from the coast, rocky peaks pierce the ice cap, itself at a mean height of around 2,000 metres (6,600 ft) above sea level, with the highest point at Jøkulkyrkja (3,148 metres or 10,328 feet) in the Mühlig-Hofmann Mountains. The other major mountain ranges are the Heimefront Range, Orvin Mountains, Wohlthat Mountains and Sør Rondane Mountains.

Geologically, the ground of Queen Maud Land is dominated by Precambrian gneiss, formed c. 1 to 1.2 Ga, before the creation of the supercontinent Gondwana. The mountains consist mostly of crystalline and granitic rocks, formed c. 500 to 600 Ma in the Pan-African orogeny during the assembly of Gondwana. In the farthest western parts of the territory, there are younger sedimentary and volcanic rocks. Research on the thickness of the ice has revealed that without the ice, the coast would be similar to those of Norway and Greenland, with deep fjords and islands.
