Anyone know what the depth of the frost line is in North Central Pa or does someone know where I can find out? Thanks Pete
Check for your area on http://www.municode.com/Resources/OnlineLibrary.asp
Otherwise, talk to your city/county building office.
I think I've seen maps in various how to build books. None handy right now. But there may be one here (there's not, it turns out, but it might be a useful publication to have):

In addition, asking a local builder sounds like a good idea.
And there's an interesting discussion here on the subject.

If PA-Builder drops in he may know. He built a nice cabin in PA.
My foundation guy knew the frost situation in my area. Also, the building inspector was clear about this when issuing my permit.

Elucidate us. 5 feet , 6 feet??
Thanks everyone for the info. I plan on going down 36" for my piers to be safe.
4 ft in Eastern Canada- 1000 miles north of PA. In my case, I'm going down 3 feet and burming up 1 foot to get 4 ft. below frost. (the burming gives a nice slope away from the cabin so water runs away.)
36" - 42" should be OK for the northern tier of PA since usually there is snow cover during the coldest parts of the year. However, I would go 48", erring on the side of caution.
