floe

They have gone out on an ice floe with no obvious way back to shore.

Not that Western civilization has never embraced the mythical Inuit practice of leaving the old out on an ice floe.

There's a clear passage through the floe, and clear water beyond, the lookout says.

No craft like the Grampus could work through a floe, What knots she could run, and what tons she could stow!

"Be ready, now," said Kit; when some one of the party on the floe fired on a sudden.

About seven o'clock we heard a splashing out along the floe.

We towed the carcass up to the edge of the floe, and pulled it up.
