Take a good look at the northern rim of that hole. What is that white stuff? To me it looks like something is venting out of that hole. Like watervapour. Such features have so far only been found on volcanoes at high altitudes but it also shows that such undergound cave formation do exist on Mars and could exist elsewhere. They could quite possibly be harbouring a natural and slightly pressureized environment where liquid water could exist in combination with higher concentrations of gasses like CO2, nitrogen and even oxygen. If so then all that is missing for life to exist is an energy source. In the case of this, and other collapsed caves on Mars, the only energy source could also spell the end of that fragile environment. It would have to be geothermal heat and the slightest shudder from a "Marsquake" could cause the whole place to come crashing in exposing whatever might have lived there to the deadly Martian surface environment. These caves could very well have collapsed because of quakes as the are all residing on the side of a huge volcanoe.

If it's on the side of a volcano then it's most likely just above one of the vents which then collapsed.
Not sure if I'd predict life for sure just yet as it's likely to be even colder then the surface due to lack of sunlight, but it has the advantage of being away from the solar radiation so anything that has survived would be able to sit there in relative safety. Even amino-acids would be a good sign.
If they found heat down there then things would get *very* interesting as that could well result in full blown life existing right now. There is some evidence that water has been rising in the frozen areas so that would suggest heat, so you never know.

I read that life probably wouldn't be connected to the caves found; it's up on one of the volcanos, where the already-thin air is even thinner. Not likely to hold life.

Maybe, but I think not. Mars is just too hostile for life. I predict that no native life, no matter how simple, will ever be found on Mars, not even under ground.

Possibly. That's all. Possibly.
