Near the Outlet from Ladon Basin
ESP_026429_1650 Science Theme: Landscape Evolution

This image is from the floor of Ladon basin near the outlet at Morava Valles.

Based on the occurrence of numerous valleys and the larger Ladon Valles that all terminate along the margin of the basin, it has been speculated that a lake once existed here. If that were the case, images of the materials filling the basin might reveal layers and structures that shed light on the responsible depositional processes.

Although a variety of variably bright materials do occur in this image, they appear largely devoid of layering. Comparision with the appearance of basin fill from elsewhere may provide context for understanding their orgin as possibly related to deposition in water or by alternate processes.
