Caves on Mars?
RockDoctor writes "The BBC is reporting that the photo-surveying of Mars has revealed seven suspected cave entrances in the Arsia Mons volcanic area.
This has been hinted at before — long sinuous channels in the same region have been interpreted as collapsed 'lava tube' caves — but the scale of the suggested entrances (sheer drops of 80 to 130m from the surrounding surface) makes my troglodytic hands twitch for my abseiling gear."
To some of us, it is news. To be completely honest, it had never occurred to me that there would be caves on Mars.
