The cutoff Formation as exposed here includes facies of the upper San Andres-lower Cherry canyon facies tract not exposed anywhere else in the Guadalupe Mountains. This study correlates the cutoff Formation in Last Chance canyon biostratigraphicly with other exposures of the Cutoff and uses that information along with sedimentological information to establish correlatable depositional sequences.application/pdfCopyright is held by the author who has granted the Oklahoma State University Library the non-exclusive right to share this material in its institutional repository.
