MARS RECONNAISSANCE ORBITER HIRISE IMAGES
November 13, 2014

o Spring in Inca City I Spring in Inca City I

  Every winter a layer of carbon dioxide ice condenses in the
  Southern polar region, forming a seasonal polar cap.

o Spring in Inca City II
  http://hirise.lpl.arizona.edu/ESP_037811_0985

  Dark spots on the ridge show places where the seasonal polar
  ice cap has ruptured, releasing gas and fine material.

o Spring in Inca City III

  We see how the number of fans and blotches depends on the
  thickness of the ice layer and how high the sun is in the sky.

o Spring in Inca City IV
  http://hirise.lpl.arizona.edu/ESP_038022_0985

  At certain times in spring, fans take on a gray or blue appearance.
  This is the time in Inca City when this phenomenon happens.

o Spring in Inca City V
  http://hirise.lpl.arizona.edu/ESP_038299_0985

  The layer of seasonal ice has started to develop long cracks, and
  fans of dust are emerging from them.
