NASA MRO HiRISE Images: June 18, 2014

– Sand Dune Catch and Release http://hirise.lpl.arizona.edu/ESP_034084_1655

Sand dunes within within craters, raise the question: do they form from sandy materials within the craters, or are they traps for dunes traveling in their path?

– Waiting for Dust Devils http://hirise.lpl.arizona.edu/ESP_036376_2160

Dust devils are identified in images both by their cloudy form and the shadow their cloud casts on the surface.

– Moving Mass Material on a Mesa http://hirise.lpl.arizona.edu/ESP_036382_2255

This observation appears to show some type of mass movement of material down the wall of a mesa in Deuteronilus Mensae.

– Blockfall on the North Polar Layered Deposits http://hirise.lpl.arizona.edu/ESP_036436_2645

The slope in this image is steep and fractured, and a large chunk of dusty ice has tumbled down and broken apart.
