One of those lesser mountains, Dry Brook Ridge, effectively divides the town as well. The portion north of it, in the Dry Brook valley, uses the ZIP code and telephone exchange of the nearby Delaware County hamlet of Arkville. The portion to the south, containing the headwaters of the famous Beaver Kill trout stream, is likewise oriented to the Sullivan County hamlet of Lew Beach to its south, although it contains a few of its own unique toponyms such as Turnwood, its only real road junction.
