Southern Ladon Basin near the Mouth of Ladon Valles
ESP_026139_1600 Science Theme:

This image shows the southern margin of Ladon Basin just to the east of where Ladon Valles enters the basin.

Numerous variably brighter and darker layers are visible in the middle portion of the image and may be extensions of similar layers observed closer to the Valles. Such layers are similar to those seen further to the south (e.g., within Holden Crater) and may record the deposition of water and sediments into the basin during a wetter period in Mars history.

It is not known whether a lake once filled Ladon Basin, but the study of the extent and character of these and other outcrops of layered sediments around the basin may help constrain the timing of basin infilling and the geologic processes involved.
