o Possible Opaline Silica in the Central Uplift of Elorza Crater

  The distinguishing feature of this central uplift is the various
  types of bedrock that are observable at the surface.

o Eroding Terrain in Arabia Terra

  At one time this was a flat smooth terrain, but over time it has
  been eroded, most likely by the wind.

o Frosty Slopes in Late Spring

  At this time of year only south-facing slopes retain the frost,
  while the north-facing slopes have melted.

o Polar Layered Deposit Slopes
  These deposits are quite extensive and partially surround the
  South polar residual cap.
