Never having seen them elsewhere, I decided to go visit Europa and check out the Ice Geysers there. Nifty neat and all, but I succumbed to temptation, and drove my SRV over one of the large ones... and was launched damn near into orbit. I laughed so hard, then decided to see if I could actually land my SRV safely... and DID! Didn't even compromise the chassis.
I suggest it as a fun thing to try.
