Exploring ancient worlds and the plants and animals that lived in them

With all the window panes and frames out of the east wall, only one small matter stood in the way of getting the old crane out of the Quarry Visitor Center --- five vertical steel I-beams running from the foundation to the roof. The removal started with strapping a steel cable harness around the beam and attaching that to a large crane in the parking lot. Next, cut through the beam at its contact with the roof structure using an acetylene torch. Then lift, swing, and put the beam down in the parking lot. Repeat four more times.
At the end this project, the east wall of windows is just one large opening --- setting the stage for the dramatic removal of the old crane from within the Quarry Visitor Center.
