This image shows the quadrangle where NASA's Curiosity rover landed, now called Yellowknife. The mission's science team has divided the landing region into several square quadrangles, or quads, of interest about 1-mile (1.3-kilometers) wide. This will allow groups of team members to focus their analysis on a particular part of the surface.
Yellowknife is a city in northwestern Canada and a group of rocks from the same region. The rocks were formed 2.7 billion years ago from both volcanoes and sediments laid down by water, and were deposited over 4-billion-year-old rocks, the oldest known on Earth.
The image was obtained by the High-Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.
