NASA’s HiRISE Views Layered Deposits in Uzboi Vallis

New HiRISE Image of Layered Deposits in Uzboi Vallis

This newly expelled picture from NASA’s high fortitude imaging scholarship examination (HiRISE) shows layered deposits in Uzboi Vallis.

Layered deposits in Uzboi Vallis infrequently start in alcoves along a hollow and/or next where tributaries enter it. These deposits might record deposition into a vast lake that once filled Uzboi Vallis when it was temporarily dammed during a northern finish by a edge Holden Crater and before it was overtopped and breached permitting H2O to empty behind out of a valley.

Layered deposits identical to those here might sojourn recorded where they were stable from erosion during drainage of a lake. Data from a CRISM instrument onboard MRO shows that clays are within these deposits that might differ from clays found elsewhere on a hollow floor. Hence, a clays in these layers might have been cleared into a lake from surrounding clay-bearing surfaces.

This is a stereo span with PSP_008338_1525.

The map is projected here during a scale of 50 centimeters (19.7 inches) per pixel. [The strange picture scale is 52.8 centimeters (20.8 inches) per pixel (with 2 x 2 binning); objects on a sequence of 158 centimeters (62.2 inches) opposite are resolved.] North is up.
