I would agree that your snow is probably wetter or heavier, but I think the 12" is about right for us.Unfortunately, with the wind it didn't set on the wheat, so not as much there, but I'd guess we got 10" or so.
And now I know why Dad wanted to put a dozer on the front of our 4wd so bad. Been pushing snow w/ a 4630 and loader, and man does that suck.
