Colorful Layers in the Walls of an Unnamed Crater

April 20, 2008

This image shows an unnamed, bowl-shaped impact crater located in the Southern Highlands. The crater is approximately 4 kilometers (2.5 miles) in diameter and 600 meters (2,000 feet) deep.

The colors depicted in this image are not those we would see with our naked eyes. An infrared band and two visible bands (red and blue-green, respectively) have been combined to produce this false-color image. False color combinations are often utilized to look for subtle compositional differences that may not be evident in true color images.

This image also (enhanced to exaggerate color contrast) shows part of the north-facing walls of the crater, deeply carved by landslides. Rocky layers, mostly purplish in color, can be followed for hundreds of meters, poking through the loose materials that cover the slopes. Locally, the rocky layers show patches of diverse colors (blue, green, yellow.) These colors may be indicative of compositional differences in the rocky layers.
