Deposits in Electris
Deposits in Electris
PSP_009029_1430  Science Theme: Landscape Evolution
This observation reveals a portion of a long outcrop of a deposit in the Electris region of Mars.

The Electris deposits occur over a range of landforms and relief and the process(es) responsible for their emplacement remain speculative.

Close examination of the outcrops reveal layering that in some places appear to include meter-scale blocks. Comparison with other HiRISE images of the deposit will enable more detailed mapping of its extent and nature and should provide new insight into the origin of these enigmatic materials.
