[TheForge] Is anyone on-line ? OT: Washed away?

Screw pile? What's wrong with driven piles? So long as you don't get too 
carried away with end bearing the skin friction will keep them from jacking 
from freeze thaw. Virtually any foundation that penetrates the freeze zone 
has to allow the soil to slip in freeze thaw or it'll be jacked out of the 
ground. If by screw pile you're referring to some kind of auger it'd have 
far too solid a grip in the freeze zone and you'd end up with one of those 
carnival tilte houses.
