 The Falls also inspired "Catterskill Falls", a poem by William Cullen Bryant.The falls, like the clove and creek with which they share a name, are a relatively recent addition to the Catskills in terms of geologic time.They evolved through stream capture at the end of the Illinoian Stage, when runoff from the glacial melt that created North-South Lake began to flow away from the nearby headwaters of Schoharie Creek and down the steep slopes of the newly created clove.
