[Rockhounds] Remains of an ancient glacier spotted on Mars

[Kreigh Tomaszewski]

The remains of a glacier have been found near the Martian equator,
suggesting that some form of water could still exist in a region on the red
planet where humans may one day land.

The ice mass is no longer there, but scientists spotted telltale remains
among other mineral deposits near Mars’ equatorial region. The deposits
there usually contain light-colored sulfate salts.

When scientists took a closer look, they recognized the features of a
glacier, including ridges called moraines — debris deposited or pushed by a
moving glacier. The research team also spotted crevasse fields, or deep
wedge-shaped openings that form inside glaciers.

The findings were shared Wednesday at the 54th Lunar and Planetary Science
Conference in The Woodlands, Texas.
