HiPOD 18 Jan 2023: A Cone-Shaped Pit on South Polar Deposits

This image is part of a stereo pair covering this strange pit on the edge of the South Polar residual cap. This will be the third stereo pair acquired by HiRISE over this feature, to measure any changes in the depth and shape of the pit over time, as it might be actively collapsing due to loss of carbon dioxide ice from the subsurface.
