Greenstone Falls is an 80-foot waterfall located on a small tributary of Stroud Creek near Stroud Creek Falls. It drops in a series of steeply-sliding tiers about 0.1 mile from the Stroud Creek confluence. There is no trail up this tributary, but it can be accessed via steep bushwack from the old trail along Stroud Creek.
