icebound

For one thing, it is always ice-free, whereas the eastern route is icebound for five months in the year.

They, too, feed the northern health stations in icebound ports where submersibles dare not rise.

Deep was the silence of the icebound shore that day, sparkling the blue waters across which the sun marked a glittering track.
