NASA Mars Reconnaissance Orbiter HiRISE Images – April 11, 2012

– Terraces or Strata on a Crater Slope http://hirise.lpl.arizona.edu/ESP_025370_1290

Structural features cut through the layered material and strata at this location. Could these features be faults or dikes?

– A Volcanic Pit Chain and Dust Avalanches http://hirise.lpl.arizona.edu/ESP_026249_2025

The upper wall of the pit shows at least four distinct layers, each representing a sequence of one or more lava flows.

– Eroded Terrain Near Volcanic Fissures http://hirise.lpl.arizona.edu/ESP_026303_1945

This observation was taken to investigate the topography near the source of fluids from the Cerberus Fossae fractures in the Elysium Planitia region of Mars.

– Layered Sediments in Danielson Crater http://hirise.lpl.arizona.edu/ESP_026349_1885

These layered sediments are of great interest because they are very regular in thicknesses.
