Lauth Crater and the Frozen "Pseudo-Lake" of Vastitas Borealis (CTX Frame - Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)

The right side of PSP_001700_2505 shows a portion of a Frost Patch on a Mound inside a Northern Hemisphere Crater (unofficially known as "Lauth Crater").
The Frost Patch has remained largely stable at least since the Viking era (late 1970s). The bright Frost Region is bounded by a Dunefield on the North-East. Several sizes of Dunes are visible. The size classes probably represent generations of Dunes that formed under a variety of dominant wind conditions.
