Description
Broken sandstone beds of the Frontenac Formation in the upper plate of a thurst fault zone at the international border on Route 201. Note prominent sub-horizontal bed near bottom of image. The second image is from the same large road cut and shows steeply dipping beddding and a fold toward the right side. Bedding is highly distrupted by faulting. Note that much of this roadcut was destroyed by subsequent improvements at the border crossing.
