Being the case with these inter-lying planes, they are highlighted by weathering which has made them appear quite prominent. Sandstones of the massive form usually show one of two forms of lamination; horizontal or cross stratification. In the case of the Jacobsville Sandstone, horizontal is more dominant where as the cross stratification appears more in freshly exposed vertical cliffs. Evidence that the Jacobsville Sandstone formed in a lacustrine environment versus a lenticular environment emerges from the distribution of substantial sandstone facies that were separated from an originating area. This particular feature is more common amongst lacustrine environments that belong to an intermountain
