iPod iChing - Liquid on Mars

Cold and snowy friday, and we ask the iPod: wazzup with the water on Mars thing?
Are the intermittent outbursts really liquid water, and what does it all mean?

Whoosh goes the randomizer.
Whoosh.

Wow. Good covering.
The Crossing is a polite euphomism about farting, clearly alluding to the well known issue of free methane on Mars and its postulated biogenig origin.
The Crown is spot on, the Hunters have arrived.
The Root also nails the issue.
The Past is curious, may refer to the issue of wanting to learn what life is like in general, and our perception of ourselves as special.
The Future is a bit worrying, although the suggestion we need to reject convention and seek independent perspectives is intriguing.
The Questioner - hmm, no comment.
The House suggests we are all delusional, or at least in two minds.
The Inside tells us that we need to grind on, and get on with life.
The Outcome though is most intriguing of all - it is a chanted rhyme that is part of a children's game, which tells you the "ring" (that which you seek) is hidden in the green hollow, and the task is to go find it given the clues before the song stops.

Wise is the Mighty iPod.
