You're right, too much dust cover. I wonder if they've seen any yellowish areas at all in the outcrop images, maybe when they drill. :)

I'm curious as to how hard (to drill) this outcrop is going to be. It looks fragile as if it's been cracking in pieces as it slides down. There are a large number of cracks... many are 'hairline' size.
