frost-bound

The roads were frost-bound and the trees leafless.

Amsterdam, and crossing the ice with his cavalry took the Dutch fleet, as it lay frost-bound at the Texel.

Snow lay on the upper hills, grizzling the brown sheets of bracken, and dappling the green velvet of the sloping ling; the valley below was frost-bound.

The little cavalcade sped swiftly on, for the frost-bound roads were pleasant travelling, and towards evening a dim mass appeared on the horizon, which presaged a fall of snow.

There was a quick movement all through the court like a ripple upon still water, and then, absolute silence--the silence of a night frost-bound and empty.
