creature in the gorge

Deep within Oneonta Gorge when the water was low I came across this rock which almost looked like some prehistoric creature with just it’s back breaking the surface of the water.  This gorge goes back surprisingly far and if you get all the way to the end (requires swimming even when the water is low) you’ll find an amazing waterfall!
