THEMIS Image of the Day, June 10, 2019. Today’s VIS image shows part of the summit caldera of Arsia Mons. Arsia Mons is the southernmost of the three large Tharsis volcanoes. Extensive lava plains originated from eruptions of this volcano.
On the left side of the image are two hills with linear depressions at the top. These features are vents where localized eruptions created small volcanoes.
