Sif Glacier
Sif Glacier ( da, Sifs Gletscher), is a glacier in northern Greenland. Administratively it belongs to the Northeast Greenland National Park. History The Sif Glacier was seen during aerial surveys by Lauge Koch and was named after Sif, the goddess representing Mother Earth in Norse mythology. The glacier was first explored from the ground by the British Joint Services Expedition in 1969. Geography The Sif Glacier is a slow-moving glacier located in Johannes V. Jensen Land, roughly in the middle of the Roosevelt Range. It flows in a WSW/ENE direction from the ice cap of the Mary Peary Peaks, bifurcating south of the Birgit Koch Peaks with one arm flowing roughly northwards and another southwards until their terminuses in the Northern and in the Southern Tvillingesø (Twin Lakes) respectively. The northern branch of the Sif Glacier ends in a valley open to the north with its mouth in Constable Bay, where it formed prominent terminal moraines in the past. See also *List of glac ...

Valley Glacier
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. ...

Roosevelt Range
The Roosevelt Range or Roosevelt Mountains ( da, Roosevelt Fjelde) is a mountain range in Northern Greenland. Administratively this range is part of the Northeast Greenland National Park. Its highest peak is the highest point in Peary Land. Located about from the North Pole, the Roosevelt Range is the northernmost mountain range on Earth.2002 American Alpine Journal, p.286 History The mountain chain was named by Robert Peary after U.S. President Theodore Roosevelt, who would become one of the main backers of Peary's 1905 Arctic expedition. During the first half of the 20th century the range was quite unexplored, except for the mapping from the coast in 1907 of the Daly Range by Johan Peter Koch, Aage Bertelsen and Tobias Gabrielsen, the northern team of the ill-fated Denmark expedition, as well as aerial surveys and mapping begun by Lauge Koch in the 1920s. In 1953 a geological expedition crossed the range through the ''Polkorridoren'' pass from Frigg Fjord to Sands Fjord. The ...

Peary Land
Peary Land is a peninsula in northern Greenland, extending into the Arctic Ocean. It reaches from Victoria Fjord in the west to Independence Fjord in the south and southeast, and to the Arctic Ocean in the north, with Cape Morris Jesup, the northernmost point of Greenland's mainland, and Cape Bridgman in the northeast. History Ancient settlements Peary Land was historically inhabited by three separate cultures, during which times the climate was milder than presently: *Independence I culture, Paleo-Eskimo (around 2000 BC, oldest remains dating from 2400 BC) *Independence II culture, Paleo-Eskimo (800 BC to 200 BC) *Thule culture (ancestral to the modern Inuit, around AD 1300) Peary's explorations The area is named after Robert E. Peary, who first explored it during his expedition of 1891 to 1892. Originally, Peary Land was believed to be an island, separated from the main island by the so-called Peary Channel, an assumed connection between Nordenskiöld Fjord and Independe ...

Moraines
A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Provenà ...

Constable Bay
Constable Bay ( da, Constable Bugt) is a bay in the Wandel Sea, Northern Greenland. Administratively Constable Bay and its surroundings belong to the Northeast Greenland National Park. Constable Bay is the northernmost bay in the world. The area of the bay is uninhabited. History The bay was named in 1900 by Robert Peary after James M. Constable, a prominent member of the Peary Arctic Club in New York.R. E. Peary, ''Report of RE Peary, CE, USN, on Work Done in the Arctic in 1898-1902'', 1903 - JSTOR Geography Constable Bay lies in the northernmost shore of Peary Land, in Johannes V. Jensen Land, about west of Bliss Bay and about east of Cape Morris Jesup. It is a fairly large indentation, with Cape James Hill rising at its eastern end.''Prostar Sailing Directions 2005 Greenland and Iceland Enroute,'' p. 130 The bay is clogged by fast ice the year round.

Glacier Terminus
A glacier terminus, toe, or snout, is the end of a glacier at any given point in time. Although glaciers seem motionless to the observer, in reality glaciers are in endless motion and the glacier terminus is always either advancing or retreating. The location of the terminus is often directly related to glacier mass balance, which is based on the amount of snowfall which occurs in the accumulation zone of a glacier, as compared to the amount that is melted in the ablation zone. The position of a glacier terminus is also impacted by localized or regional temperature change over time. Tracking Tracking the change in location of a glacier terminus is a method of monitoring a glacier's movement. The end of the glacier terminus is measured from a fixed position in neighboring bedrock periodically over time. The difference in location of a glacier terminus as measured from this fixed position at different time intervals provides a record of the glacier's change. A similar way of trac ...

Mary Peary Peaks
The Mary Peary Peaks ( da, Mary Peary Tinder) are a mountain in the Roosevelt Range, Peary Land, Northern Greenland. Administratively they belong to the Northeast Greenland National Park. The peaks were named by Robert Peary after his mother, Mary Peary (1827 – 1900). Peary saw the mountain from a distance, in the vicinity of Constable Bay, as he traveled along the shore. He marked it in his map but did not go inland to explore the features of the range. Geography The Mary Peary Peaks are located in the middle sector of the Roosevelt Range east of the Polar Corridor in a roughly central position to the west of the western end of the H. H. Benedict Range.Google Maps The maximum height is . According to the A-5 sheet of the Defense Mapping Agency Navigation chart it is a summit.

Ice Cap
In glaciology, an ice cap is a mass of ice that covers less than of land area (usually covering a highland area). Larger ice masses covering more than are termed ice sheets. Description Ice caps are not constrained by topographical features (i.e., they will lie over the top of mountains). By contrast, ice masses of similar size that ''are'' constrained by topographical features are known as ice fields. The ''dome'' of an ice cap is usually centred on the highest point of a massif. Ice flows away from this high point (the ice divide) towards the ice cap's periphery. Ice caps have significant effects on the geomorphology of the area that they occupy. Plastic moulding, gouging and other glacial erosional features become present upon the glacier's retreat. Many lakes, such as the Great Lakes in North America, as well as numerous valleys have been formed by glacial action over hundreds of thousands of years. On Earth, there are about of total ice mass.

Johannes V
Johannes is a Medieval Latin form of the personal name that usually appears as "John" in English language contexts. It is a variant of the Greek and Classical Latin variants (Ιωάννης, ''Ioannes''), itself derived from the Hebrew name '' Yehochanan'', meaning "Yahweh is gracious". The name became popular in Northern Europe, especially in Germany because of Christianity. Common German variants for Johannes are ''Johann'', ''Hannes'', '' Hans'' (diminutized to ''Hänschen'' or ''Hänsel'', as known from "''Hansel and Gretel''", a fairy tale by the Grimm brothers), '' Jens'' (from Danish) and ''Jan'' (from Dutch, and found in many countries). In the Netherlands, Johannes was without interruption the most common masculine birth name until 1989. The English equivalent for Johannes is John.

Greenland
Greenland ( kl, Kalaallit Nunaat, ; da, Grønland, ) is an island country in North America that is part of the Kingdom of Denmark. It is located between the Arctic and Atlantic oceans, east of the Canadian Arctic Archipelago. Greenland is the world's largest island. It is one of three constituent countries that form the Kingdom of Denmark, along with Denmark and the Faroe Islands; the citizens of these countries are all citizens of Denmark and the European Union. Greenland's capital is Nuuk. Though a part of the continent of North America, Greenland has been politically and culturally associated with Europe (specifically Norway and Denmark, the colonial powers) for more than a millennium, beginning in 986.The Fate of Greenland's Vikings , by Dale Mackenzie Brown, ''Archaeological Institute of America'', ...
