> The little hoodoo formations in the upper right of the image...
My first impression is that they are little Wopmays. I'm looking at eariler images, pre-entry, along the top of Burns Cliff, in the Sol 123-127 range. I'm sure we'll look at that once we get to the rim, but I can't wait.
Those dark strips are indeed just plain weird. Look like weathering in joints, but we'll see what closeups look like.
Whew.
