Spirit is currently sitting near some holey rocks of some sort. Any guesses as to what kind of rock that is?

Nah. That's just proof that buckshot was used in the alien wars.

Looking at the leeward side of some of the rocks there seems to be sand/dust accumulations drifted in so I guess the area is pretty windy and the features are caused by wind erosion. Some of the 'holes' might not be holes but blueberries, difficult to determine from that photo as it's a bit fuzzy. From the shadow cast on the sundial we are looking almost directly toward the sun so we are seeing the dark shadow side of any protusions. They do look like holes though so I'm still undecided/going with wind erosion at the moment.

It does apear that Martian ?sedimentary? rock is fairly soft as would be expected from a low g/high radiation envrionment and it has also had a lot of years being sandblasted so odd forms will be produced. I've seen similar sort of wind erosion on soft sandstone so I'm not too surprised by this pic.
