Abstract: [1] Secondary crater fields are important stratigraphic markers that can shed light on resurfacing processes that have occurred since their formation. We examine the morphologies of secondary craters formed from the ejection of material from two large impacts on the Martian South Polar Layered Deposits (SPLD): McMurdo crater at 84.5°S, 0°W, and an unnamed impact at 80.8°S, 284°W. The morphologies of these secondary craters allow us to impose constraints on the modification history of the SPLD. We have quantif…
