More Preparation

While I had the compressor running, I figured I'd do a quick blast on what will probably be a very challenging prep this winter, as well as preparing some "low-hanging fruit" in the form of a prone.

First, the investigative quick air abrasion blast on this Greenops widderensis roller with flying genal spines. This one will certainly be a major challenge to do without screwing up. I'll probably end up cutting the rock a bit above the spines and delicately work my way down to reveal the other side. 

This was the low-hanging fruit: a small Eldredgeops rana prone from my Penn Dixie weekend. The matrix is very thin on one side, so there was the risk of the trilobite flaking.
