Frost Patch and Dunes in a Northern Hemisphere Crater

February 7, 2007
The bottom half of PSP_001700_2505 shows a portion of a frost patch on a mound inside a northern hemisphere crater. The frost patch has remained largely stable at least since the Viking era (late 1970s).

The bright frost region is bounded by a dune field on the northeast. Several sizes of dunes are visible. The size classes probably represent generations of dunes that formed under a variety of dominant wind conditions.
