The West Castleton Fold was the subject of my second ever (non-robotic) GigaPan (http://share.gigapan.org/viewGigapan.php?id=1204).
This shot illustrates the axial region of a recumbant syncline in the Poultney Formation of the Giddings Brook Slice of the Taconic Allochthon. This outcrop is a textbook example of axial cleavage-bedding relations in the hinge of a fold. There are some remarkably ptygmatically folded quartz-rich layers interbedded with the slates.
Although the light was not optimal when I visited it this summer, I was able to shoot a far more detailed GigaPan using the Epic100 robot. Light was fading as sunset approached, so I've taken this shot into Photoshop in order to try to optimize the image. The original (pre-photoshopping) metadata is included below:
