Gullies on Mars form during the winter, fluidized by carbon dioxide frost, so we monitor these sites for activity throughout the year.
This mid-winter scene is almost completely frosted over the pole-facing slope within the shadow.
The map is projected here at a scale of 50 centimeters (19.7 inches) per pixel. (The original image scale is 50.5 centimeters [19.9 inches] per pixel [with 2 x 2 binning]; objects on the order of 152 centimeters [59.8 inches] across are resolved.) North is up.
