[AT] OT - bridge replacement

[charlie hill]

Ken,  my guess was that Mattias was talking about anchoring the bridge into 
the permafrost but I don't know.
I also don't know of anywhere in the US other than Alaska that has 
permafrost.
Here where I live the frost line is about 8" and we haven't seen it freeze 
that deep in a number of years.
Maybe someone can fill us in on the frost line in the northern states. 
Ralph answered that same question
about his location in Saskatchewan a while back I believe but I don't 
remember the details.

Charlie, Mattias

Permafrost and freeze-line are in that area. In my experience:
Freeze-line is how deep the ground freezes during winter.
Permafrost is permanently frozen ground (think parts of the Arctic that
never thaw).

Back in Montana the freeze-line would get to 6 feet and water lines had to
be deeper than that.
Here in Central AZ the freeze line is about 1/4". Ground temp during summer
here is usually above 80 degrees and pools have to be cooled.

Spring has arrived here... the peach and apple trees are in full bloom and
the citrus is falling off the trees. Great tractor weather!
