Read all the papers & came up with nothing. So, here are some pics of my activities in the last few days. We'll start with circling vultures. The pic shows 6, but I had 7 over my head. I was at an abandoned marble quarry in northern Wisco, collecting some samples. The other pics are of the quarry, along with some undisturbed rock & a glacial erratic, moved three miles south by the glacier in the last ice age.
