This thread is for those rockhounds among us to discuss the new terrain we'll see as Perseverance scoots around her new home. Let's get dirty & technical! laugh.gif

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

The models for the evolution of Séítah, Máaz etc are compelling. The only query I would have is the timeline for the beginning of cyclical inflow to the crater. That is, did this begin prior to basaltic emplacement because Guillaumes at the deepest exposure seems sedimentary.
