Currently about 1,060 pits were found on Mars. Most of them are located in the huge Tharsis elevation and if some of them are caves then they are likely lava tube types of caves. Besides lava tube caves for which there is abundant evidence, the existence of other more elusive types of caves on Mars is also discussed.

Intro and outro was made with Space Engine.
