This image was a public request to take a closer look at these deposits, as well as to complete a stereo pair and create a digital terrain model. These products can help us measure the thickness of the deposits. Layers may be formed by groundwater rising up to deposit minerals and cementing sediments.
Arabia Terra is one of our favorite regions to image, mainly due to the diversity and beauty of its layered deposits.
