MAHLI view of "Gillespie Lake," a coarse sandstone on the edge of Yellowknife Bay, sol 132
Filed under pretty pictures, Mars, Curiosity (Mars Science Laboratory)
Curiosity held its MAHLI camera within 3 centimeters of a ledge on sol 132 to examine its grains up close. The investigation revealed the rock to be a coarse sandstone, made up of cemented grains of a range of sizes. The biggest grains at lower left are about 2 millimeters long, which is larger than sand; technically, they are classified as "granules." The whole view is about 4.3 centimeters wide; at full resolution, it is about 26.1 microns per pixel.

Here is an annotated version of the image. Also of interest is this MAHLI image, showing the same area of the rock from a greater distance. Here and here are Hazcam views of the position of the arm for both the closer and farther-away photos, and here and here are Navcam views.
