Space/Science » in reply to Well, Nick?..You're Mars theory has received it's most vital support evidence to date.

Tharsis Bulge.

yes, the entire Tharsis bulge is Isostatically compensated (but the nature of isostacy is that large things compensate faster than small things due to the larger forces and length-scales).

The Ages at which things occurred also matter - as the crust cooled and thickened, topography and gravity anomalies became "locked in" at progressively larger spatial scales. Most of the compensation occurred "early" - say the first 500 Ma of mars' evolution.

When areas of Mars are looked at in detail, we see many overlapping processes and timescales!
