Triton - Voyager 2

Dark streaks on the south polar region of Neptune's moon, Triton

Voyager 2 image of the south polar terrain of Neptune's largest satellite, Triton. This image shows about 50 dark plumes on the surface of the polar cap. These streaks originate at dark spots a few kilometers in diameter and some are over 150 km long. The deposits may be vented plumes of material transported to the northeast by winds. North is up, the boundary of the bright south polar cap can be seen towards the top of the image. (Voyager 2, P-34714)
