Orion Massif from Creswick Peaks

Orion Massif is a prominent massif located in Palmer Land, Antarctica. It is 14 nautical miles (26 km; 16 mi) long and consists of a complicated network of peaks, passes, ridges, and cirques. It is located 4 nautical miles (7.4 km; 4.6 mi) east-northeast of Scorpio Peaks, between the upper parts of Meiklejohn and Millett Glaciers, and 5 nautical miles (9.3 km; 5.8 mi) south of Goettel Escarpment.

In geology, a massif is a section of a planet's crust that is demarcated by faults or flexures. In the movement of the crust, a massif tends to retain its internal structure while being displaced as a whole. The term also refers to a group of mountains formed by such a structure.

Palmer Land geographic region

Palmer Land is the portion of the Antarctic Peninsula, Antarctica that lies south of a line joining Cape Jeremy and Cape Agassiz. This application of Palmer Land is consistent with the 1964 agreement between US-ACAN and UK-APC, in which the name Antarctic Peninsula was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69 degrees south.

Antarctica Polar continent in the Earths southern hemisphere

Antarctica is Earth's southernmost continent. It contains the geographic South Pole and is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14,200,000 square kilometres, it is the fifth-largest continent. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages 1.9 km in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula.

It was named by the United Kingdom Antarctic Place-Names Committee in 1976 after the constellation of Orion.

Orion (constellation) Constellation straddling the celestial equator

Orion is a prominent constellation located on the celestial equator and visible throughout the world. It is one of the most conspicuous and recognizable constellations in the night sky. It was named after Orion, a hunter in Greek mythology. Its brightest stars are the supergiants: blue-white Rigel and red Betelgeuse.

Gothic Mountains

The Gothic Mountains is a group of mountains, 32 kilometres (20 mi) long, in the Queen Maud Mountains of Antarctica, located west of Watson Escarpment and bounded by Scott Glacier, Albanus Glacier, and Griffith Glacier. The mountains were first visited in December 1934 by the Byrd Antarctic Expedition (ByrdAE) geological party led by Quin Blackburn. The name was proposed by Edmund Stump, leader of a U.S. Antarctic Research Program (USARP) - Arizona State University geological party which made investigations here in the 1980-81 season. The mountains are composed of granites which have weathered to produce a series of spires and peaks reminiscent of a Gothic cathedral.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
