Buttermilk Falls 

This one is big fun; the approach can be a bit treacherous, especially if there is no snow, just wet leaves over slippery shale slabs. And take care not to punch through when crossing the creek.

No need to rap P1, 2, 6, or 7. Look for tracks off to the side: climbers' right on P7, CL on the others. If you don't see fixed slings, it's because there's a walk-off. Lots of folks rap P7 and bust the ice underneath before it has a chance to fill in; please don't be that guy.

Does any one know how how Buttermilk gets affected when there is a lot of snowfall? Avalanche danger?

It is probably much easier to descend with a lot of snow especially with snowshoes. It can be treacherous with rocks and falling through ice with little snowpack. No avalanche hazard here.

anyone know what township this is in ?

I'm not a local and found Kaaterskill Falls proper (which is not on this site but had numerous easy, and very steep routes) instead of Buttermilk falls but I am fairly certain that it falls on 23A somewhere between Haines Falls and Palenville there is quite a bit of ice on that stretch. With the given directions I'm still unsure, more cross referencing to other parking areas and other routes will be required before I understand, but there is plenty of see a climb and walk to it options on 23A so that anybody could get by for a number of days down there.

Ryan - there's a full page map in the Catskill Ice guidebook that makes the location of Buttermilk and the other Rt 23A climbs very clear.
