We analyze Kodiak, an eroded delta remnant in Jezero Crater, Mars, using several hundred images from the Mastcam-Z and SuperCam instruments on the Mars 2020 Perseverance Rover. We create a high-accuracy digital terrain model to measure Kodiak’s stratigraphic layers, which we divide into three units and characterize individually. While each unit possesses geometries interpreted as consistent with a Gilbert-style delta formation, the older units exposed on Kodiak’s north to northeast sides include more complex layered structures with azimuthally varying foresets. We compare Kodiak’s northeast foresets with the clinoforms of Whale Mountain, an outcrop exposed in the Western Jezero Delta scarp, and show similar azimuthally varying foresets. The stratigraphic analysis presented herein (strike and dip, unit thickness, etc.) will help test and refine detailed sedimentological hypotheses for the formation and evolution of the Jezero delta. Our 3D reconstruction and measurements enable unprecedented precision to evaluate depositional models and advance geological interpretation.
