Re: Fw: ice sculptures

[Richard L Whitman <rwhitman@usgs.gov>]

Here are the suggestions we got back on these strange formations.  Bill
Schuster and Vicky believe they are frozen upwellings, seem reasonable to
me too.  Rich and Vicky agree that they are unusual, these things are about
the weirdest things I've ever seen on a beach-resemble stromatoliths,
crynoids or something even alien.



Fascinating!  Looks a bit like stalagmite formation.  I'd suggest that
groundwater may be upwelling at spots on the beach and freezing in layers
as it exudes.

Frozen up-welling near shore springs. Flowing wells can result in very
similar ice formations.

It doesn't seem to appear in any of the  categories we assembled for
LakeSuperiorStreams.org.  See
http://lakesuperiorstreams.org/understanding/ice.html   and its link to
http://www.crrel.usace.army.mil/ierd/ice_guide/iceguide.htm  to the Army
Corps.

If someone turns up more information, would you please let us know so we
can add it to our website.

Thanks...Rich Axler
