Location: Fall Creek Gorge below Ithaca Falls

Description: South facing gorge wall. Notice variation in shale and siltstone beds. Differential erosion results. South facing means more effects of thermal expansion and thus more weathering. Compare to the gorge wall facing North. Notice jointing and how it impacts erosion. Thickest unbroken bed near the base is 20 cm. thick.
