The story

How Cassadaga came to be

From Wikipedia’s history of Cassadaga.

Cassadaga is a Seneca name meaning 'water under the rocks', descriptive of the natural springs of the area flowing from glacial moraines. In dry weather, many of the local streams "disappear", and the spring-fed water runs wholly within the gravelly bottoms of the stream beds draining from the surrounding hills.
