> With the presence of tides, the portion under the glacier would
rarely be completely underwater, due to the rise and ebb of the tide.
> However, the water would, over time, erode the portions of the
glacier it passed through, creating open sections of ice caverns above
the water line. Sometimes, the water might rise to fill this
completely, forcing the air in the space out in explosive bursts that
cracked off portions of glacier, but often it seems likely there would
be enough air to venture a sailing.
> Fraught and dangerous it would surely be, of course, with risk as
likely to come from plummeting icicles the size of stalactites or
sections where the passage was as perilous as the fastest of rapids,
but possible? Who knows.... only a fool would try... wouldn't they?
You know, a few despearte bands mayb have tried it since the
dawn...and if they found the occasional cavern that was somehow
habitable (geothermal vents?) then their descendants could still be
there (ignoring inbreeding for the nonce). Who knows what secrets
they took with them.....
Now to figure out why anyone would be trying to sail under there....
On a barely related note, there is a piece of land bound on the west
by the Glacier, and on the south and east by the White Sea. I think
it is essentially uninhabited. But why? Marauding Trolls? Hostile
sea deities make fishing/whaling/seal hunting not viable?
