At this pit on Mars, the steep slope at the northern edge (toward the top of the image) exposes a cross-section of a thick sheet of underground water ice. The image is from the HiRISE camera on NASA’s Mars Reconnaissance Orbiter, with an enhanced-color central swath between grayscale on each side. (NASA/JPL-Caltech/UA/USGS)
