Help ID a book for me.

I have a vague recollection of reading a book in elementary school about a group of children who, for some reason, had to hide some gold, and transported it down a hill inside their sleds. I think they were hiding it from the Nazis. Does anybody have any idea WTF I’m talking about?

Was it Snow Treasure?

That looks like it! Thanks. I like the reviews from some of the tweeny-boppers forced to read it. " this BOOK suCKS to the MAX!!" Heheheh.
