Complex Terrain East of Holden Crater
Complex Terrain East of Holden Crater
PSP_010197_1540  Science Theme: Landscape Evolution
This observation covers the Martian surface just to the east of the 150 kilometer-diameter Holden Crater in southwestern Margaritifer Terra.

The image reveals a very complex terrain, with what appear to be very blocky or polygonally fracture materials interspersed with other materials also standing in relatively high local relief. The entire surface appears etched and the blocky or fracture materials may lie on top of the sequence.

Although some of these materials likely relate to the ejecta deposit from Holden Crater, the complex appearance of the current surface makes mapping out those deposits difficult. This fascinating distribution of materials and landforms comprises a spectacular landscape the origin of which likely reflects contributions from multiple geologic processes.
