The Narrows in Onion Creek. Note my friend in the highlighted orange circle in the center of the image.
The contact between the gypsum caprock of the Pennsylvanian-age Paradox Formation (left) and overlying red sandstones and conglomerates of the Early Permian age Cutler Formation (right). Note the orientation of the dipping red beds relative to the Paradox diapir.
Exposure of the highly deformed Paradox Formation at the heart of the Onion Creek diapir. Odiferous Stinking Spring, containing sulfur-reducing bacteria, occurs at this location.
