The only thing I see in the data base so far is

surface=ice_road, six times, and
surface=ice, twice
http://osmdoc.com/en/tag/surface/#values

We find it mentioned here, under "surface=" which might not be
optimal, but is true, and observable by other mappers.

access=seasonal may be our best bet for now, given than trying to be
more-exact is likely to be more misleading.  After all, some maps
don't even show where traffic_signals are located, and drivers still
manage to obey them fairly often.  Perhaps we can count on drivers to
not drive into open water?  ;-)
