Northern Ladon Basin
ESP_026205_1635 Science Theme:

This image reveals the surface along the northern margin of Ladon Basin, near where deposits partially filling the basin meet with surrounding highlands materials.

A number of valleys terminate around the Ladon Basin margin, which is also punctuated by Ladon Valles and Morava Valles. Most of these drainages source the basin, whereas Morava drains it. Because Ladon basin lies along a larger drainage extending well to the south and into the Argyre region, sediments partially filling the basin may record a long and complicated history of infilling.

The basin once may have held a lake, though this remains uncertain. Study of the brighter sediments within the basin and visible in portions of the image may provide clues to the amount and process of infilling and help resolve this question.
