ИСТИНА

The Holden crater is located in the Uzboi-Ladon-Morava (ULM) outflow channel system in Margaritifer Terra and likely formed in the Noachain. Existing studies of outcrops suggest that there was a lake in Holden crater, and the high-energy water deposition from the Uzboi Vallis reworked the layered sediments formed in the original low-energy water environment. To study the geological processes that possibly occurred in the putative Holden Lake as it gradually dried up, we use CTX and HiRISE images and MOLA DEM to revel the geomorphological features of water level changes in the crater.
