constructed from images acquired by the Mastcam-Z cameras on the Perseverance rover during Sol 3. I’ve been drinking from the fire hose of thousands of new downloaded raw images and selected three to process and stitch together that depict the low escarpment at the delta front. The panorama clearly shows the distributary channels standing out on the upper delta plain in relief, as surrounding finer-grained sediments are swept away by the wind, coarser-grained channel deposits stand out as more prominent outcrops.
Panorama view of delta front about 1.8 km away from Perseverance rover. High crater rim is approximately 10 km distant. (Click on image to enlarge.) The former inflow channel to the delta from Neretva Vallis is in the low spot on the very left of this image.
Perseverance rover location indicated by red circle, 1.8 km from the delta front. The curved red line indicates portion of delta front seen in the first image above, and the red X (upper right corner) marks the high peak seen in the distance on the crater rim.
Screenshot showing the Horton River delta in the Canadian Arctic, a smaller but excellent terrestrial analog of the Jezero delta on Mars. These small deltaic landforms are known as a “Gilbert-type deltas,” so named after G.K. Gilbert of the U.S. Geological Survey.
Plate XXVII from US Geological Survey Monograph No. 1. (1890), Gilbert’s study of pluvial Lake Bonneville. Here the Logan River is incising into the Pleistocene-age delta deposits along the Wasatch front in Utah. Compare this diagram with the panorama of the Jezero delta on Mars.
