Yellowknife Bay Formation on Mars
This mosaic of images from Curiosity's Mast Camera (Mastcam) shows geological
members of the Yellowknife Bay formation. The scene has the Sheepbed mudstone in
the foreground and rises up through Gillespie Lake member to the Point Lake
outcrop. These rocks record superimposed ancient lake and stream deposits that
offered past environmental conditions favorable for microbial life. Rocks here
were exposed about 70 million years ago by removal of overlying layers due to
erosion by the wind.
The scene is a portion of a 111-image mosaic acquired during the 137th
Martian day, or sol, of Curiosity's work on Mars (Dec. 24, 2012). The foothills
of Mount Sharp are visible in the distance, upper left, southwest of camera
position.
