Beaverkill

  Many of the hamlets in Rockland are little more than a handful of houses surrounded by woodlands.  Beaver Kill is one of these.  Like a neighborhood in a larger community or city, its identity comes from the community itself.  There may be a history to the area, to the name, but often it's lost in the past.  Beaver Kill is such a place.  On a satellite image of the area, even fewer structures are seen there than in Anderson. Nothing is found, so far, in any of the town histories and there is not a history written, so far, of the community.  Beaverkill is also the name of one of the significant rivers in Rockland; the other being the Willowemoc.

"Though the term "hamlet" is not defined under New York law, many people in the state use the term hamlet to refer to a community within a town that is not incorporated as a village but is identified by a name, i.e. an unincorporated community."  "A census-designated place (CDP) is defined by the United States Census Bureau as "a statistical entity defined for each decennial census according to Census Bureau guidelines, comprising a densely settled concentration of population" that is not part of a city or a village "but is locally identified by a name."  Beaver Kill is not designated by the census. (Wikipedia) 

So far, I have found no historic events or individuals associated with Beaver Kill, Beaverkill Rd. follows the Beaverkill through the area and is clearly the name sake of the hamlet.

If you're traveling west on NY Rte 17 you have to exit at exit 96 which puts you on Debruce Rd. /Rte 81 which takes you to Rte 178/ Old Rte 17 on the right.  That takes you into Livingston Manor and on your right is Rte 151/Beaverkill Rd.  If you follow Beaverkill Rd. north it ends where the Beaverkill River turns east and a lesser road follows along it toward what is marked as Beaver Kill hamlet.  On Google maps, the hamlet of Beaver Kill is marked at the northern edge of the Willowemoc Wild Forest, part of Catskill Park.
