The landscape stone located at stop 1 is an example of two different sedimentary sandstone rocks that are separated by a bedding plane. The bedding plane indicates a change in the depositional environment. According the law of superposition, we assume that the rock unit located on the bottom is older than the top layer. The older rock is white in color and most likely a quartz sandstone, whereas the younger rock layer is a red color, suggesting a high percentage of potassium feldspar, and therefore is an arkose sandstone.
Small laminations exist within the quartz and arkose sandstone.
These laminations are an area of weakness and therefore, prone to increased weathering from wind and water. In fact, looking at the map view of the sandstone we see that the top-most lamination of the arkose sandstone is peeling away similar to how an onion peels into layers. Also present is a joint dissecting the rock perpendicular to the map view. The joint will widen over a period of time because of water and wind agents creating increased weathering. The rock located in these beds is fossiliferous limestone.
