A Martian glacier? This feature, about 5 km long, was found in photographs
of Mars from the Mars Global Surveyor
spacecraft,
by PSI's Mars research team. This feature is on the inner wall slope
of a large crater. The feature appears to be a tongue of material
flowing down the crater wall, and may be a "rock glacier", or glacial
mass composed of a mixture of ice and soil. PSI's Dr. Elizabeth Turtle
recently received a NASA grant to study such features on Mars. The feature
is located at 247 W longitude and 38 S latitude, a latitude zone of Mars
famous for "softened terrain" which may involve ice flow. It is located
just east of a water-flow channel system known as Reull Velles, which has
been studied by PSI's Dr. David Crown.
