...I'm not - yet - totally convinced that those thermal "anomalies' are developing or dormant geothermal sites on Mars...and the idea of "ice towers" on Mars is still little more than an interesting hypothesis in search of hard evidence.
I'm being cautious and conservative...Once bitten; twice shy.

Still...those thermal 'anomalies' in the Hellas Basin should be checked out in the future by...whatever robotic explorers are available
[Rover, penetrator probe, or robot aircraft].

I'd love the idea that there may be active geothermal sites no Mars...
Imagine! If they were to exist on Mars...even macroscopic life like "worms" [read the thread below on surviving worms from the Columbia] might be possible...
Could a worm be genetically-adapted
to survive CO2 freezing cold, and to
receive it's vital oxygen by ingesting
peroxide-rich martian dust?
Sigh! Wishful thinking.
