Best Ski Center Sauna in Northeast?

I'm on a mission to find a true finnish sauna experience (i.e., getting
whacked around with a birch branch, jumping in a lake, etc.) and am
trying to find a public place that provides the right facilities (may
be turned into an article about saunas for CCS ...)

Can anyone recommend a ski center with good sauna facilities?

(I've always liked the sauna at Craftsbury (very hot and close to back
door leading to snow banks to roll in), but it's not quite the full
Finnish formula...)

Thanks in advance,

Jon

The only Finnish sauna I know of in the Northeast, at a XC center, is
at Lapland Lakes in New York. A true Finnish wood fired sauna in the
back of the center building. Cautions: (1) it's usually not fired up
until late in the day and you may have to fool with it to get it hot
and (2) Lapland Lakes XC center is a a small piece of land and trails
constantly switch back to squeeze in the K, not very desirable.
