o Ice in a Chlorite-Bearing Escarpment in Northwest Hellas
  The image was captured at the beginning of southern spring,
  at a time period when south-facing escarpments still retain
  ices deposited during the winter.

o How Did the Mound in Gale Crater Form?

  Scientists have been wondering about the origin of the central
  mound in Gale Crater since before Curiosity landed nearby.

o Ridges and a Valley with Flow Fronts
  In this observation, we see heavily cratered terrain with deposits
  that record Martian geologic history and stratigraphy.

o Eastern Valles Marineris Bedrock Stratigraphy and Falling Dunes
  As with all dunes, wind regime, sediment supply, topography, and
  climate are all important factors in where dunes form and persist.

All of the HiRISE images are archived here:
