Day #8 Deskcrop: Baraboo Rhyolite Doorstop (GigaPan)

IMG_7273Today’s deskcrop is actually my office doorstop. It’s a glacial erratic clast of Baraboo Rhyolite recovered from the Wisconsinan Terminal Moraine in the Keller Road Quarry, just south of the Badger Army Ammunition Plant near Prairie du Sac, Wisconsin. This was the first really successful GigaPan I shot in the macro format, as well. The GigaPan captures a cut face. The color is natural and not the result of any staining or postprocessing. If you zoom around you’ll find some remarkable zoned feldspar phenocrysts.
