Frosted Gullies On A South-facing Slope Within A Martian Crater
Frosted Gullies On A South-facing Slope
This HiRISE image shows frosted gullies on a south-facing slope within a crater.
At this time of year only south-facing slopes retain the frost, while the north-facing slopes have melted.
Gullies are not the only active geologic process going on here. A small crater is visible at the bottom of the slope.
Image cutout is less than 5 km (3 mi) across and the spacecraft altitude was 254 km (158 mi). For full images including scale bars, visit the source link.
