Geology Dig!

Sam, reluctantly agreeing to a photo before heading in to camp

Today Sam goes to a geology dig! He's been in geology camp all week. Today (high of 89 deg F) they drive an hour to an old quarry to search for fossils. The quarry site says,

At Penn Dixie, you can walk on the site of a former quarry operation that was once the source of calcareous shale excavated and used for cement aggregate by the Penn Dixie Cement Company.  During the 1960s, 9 to 10 feet of shale was removed revealing 380 million year old Devonian era fossils preserved within the Windom Shale.

Apparently this area was, during the Devonian, a vast shallow tropical ocean with lots of little critters in it which silt, solidified into shale, has preserved for us.

Hoping he comes back with one.  :-)  He claims this is the best camp he's been to, and he's been to some good ones (Hochstein music & art, Memorial Art Gallery art camp, etc.).
