THEMIS: Polar cap layers at Ultima Lingula

Polar layers (THEMIS_IOTD_20190204)THEMIS Image of the Day, February 4, 2019. Today’s VIS image is located along the margin of Ultima Lingula, where the polar cap meets the surrounding plains.

The feature in the center of the image is a chasma where the ice has eroded down the the surface of the plains. The extensive layering of the polar ice was created by seasonal deposits of ice and dust.
