THEMIS Image of the Day, August 6, 2019. Today’s VIS image shows a portion of the flank of Albor Tholus, a volcano found in the Elysium volcanic complex. The pits and cracks may have formed when the volcano’s flank responded to internal lava (or gas) pressures and expanded slightly.
The caldera of the volcano is very deep compared to its height. The top elevation of Albor Tholus is approximately 4.5km, but the deepest part of the caldera measures 3km below this, making the caldera floor only 1.5km above the plains.
