I'd like a discussion thread about the geology detatched from the time limits of current MSL threads. We had a 'Geomorphology of Cape York' thread that attracted a lot of interesting posts. How about 'Geomorphology of Gale Crater'? I have one or two ideas but many more questions, and I'd like to post them in a longer-running thread away from the day to day imaging discussion. Any other takers?
For starters, does anybody have a contour map of this place like the one at Meridiani with 5m intervals? ADMIN: You have your wishes fulfilled on UMSF (sometimes) |

It's a cinch we're not going to be finding bedrock, NASA came here looking for bedrock.. didn't they.
Bedrock should be at the bottom of a deep crater, shouldn't it. We would like to fine something solid some place. No bedrock on lake affect... if the area is below the frost line. |

It's a cinch we're not going to be finding bedrock.... Gale crater is easily old enough for bedrock to have formed in it from once loose material that filled the crater. I think the mission is not to discover material from the surface that existed before the impact that formed Gale Crater. I think the mission is to learn the deposition history of the material that later filled the crater. That history is preserved in bedrock that formed long after the crater's creation and which now lies exposed in Mount Sharp and the area around it that Curiosity is currently exploring.
