My guess is they will travel south along the base of the hills to examine outcrops that they have seen from MOC images. That could take months, and we are at least 1.5 months away from the hills now. So any likely climb to the top of one of those hills may have to wait a while. Probably not before the September communication black out.

There is one hill that does appear to have a crater at the top and some possible exposed bedrock. That would seem the likely one to climb. Whether it is climbable I have no idea. There apears to be a slope going up but from this angle it is difficult to see how steep it is. Remember, Opportunity had some trouble getting out of eagle crater and experienced some slippage. That would indicate a significant risk factor for Spirit in trying to climb the hill. That's a good reason to postpone any hill climbs until later in the mission once they've gotten a good look at bedrock along the base of the hills.
