Link
"Link" rock outcrop on Mars - an ancient streambed[1][2][3] viewed by the Curiosity rover (September 2, 2012) (3-D version).
Feature typeRock outcrop
Coordinates4°35′S 137°26′E / 4.59°S 137.44°E / -4.59; 137.44

Link is a rock outcrop on the surface of Aeolis Palus, between Peace Vallis and Aeolis Mons ("Mount Sharp"), in Gale crater on the planet Mars.[1][2][3] The outcrop was encountered by the Curiosity rover on the way from Bradbury LandingtoGlenelg Intrigue on September 2, 2012 (the 27th sol of the mission), and was named after a significant rock formation (and lake) in the Northwest TerritoriesofCanada.[4] The "approximate" site coordinates are: 4°35′S 137°26′E / 4.59°S 137.44°E / -4.59; 137.44.

"Goulburn", "Link" and Hottah" rock outcrop - suggest "vigorously" flowing water in an ancient streambed (September 27, 2012).
The sedimentologyof"Link" (left) is strikingly similar to a terrestrial fluvial conglomerate (right).

The outcrop is a well-sorted gravel conglomerate, containing well-rounded, smooth, abraded pebbles. Pebbles and gravel a few millimeters to centimeters across are embedded in amongst a finer, white matrix. This outcrop geology is strikingly similar to some terrestrial fluvial conglomerates.[5] Around the rock are scattered well sorted loose gravel around 1 cm across, which are thought to be weathering out of the outcrop.

The rock has been interpreted as a cemented fluvial sediment, deposited by a "vigorously" flowing stream, probably between ankle and waist deep. This stream is part of an ancient alluvial fan, which descends from the steep terrain at the rim of Gale crater across its floor.[2]
