hard freeze meaning in English

坚冻

The horse clattered along the hard frozen road
马从坚硬结冻的路上得得地走过。
To mend the matter , when we came to pampeluna , it continued snowing with so much violence , and so long , that the people said , winter was come before its time , and the roads which were difficult before , were now quite impassable : for in a word , the snow lay in some places too thick for us to travel ; and being not hard frozen , as is the case in northern countries : there was no going without being in danger of being bury d alive every step
这一段路本来就不好走，现在更是无法通行了。有些地方积雪很深，寸步难行而且，这一带的雪不像北方那样冻得结结实实的，而是很松软，因此走在上面随时有被活埋的危险。我们被阻在潘佩卢那不下二十天，眼看冬季已到来，天气没有转好的可能，因为这一年是人们记忆中欧洲最严寒的冬天。
