Answer: Based on your description I am not sure what happened to your crocuses. Usually they are very cold tolerant and will even bloom through a light snow, so the cold itself would not necessarily hurt them. A heavys now would be an insulating layer, so I would have expected them to pop through the melting snow, and you would have seen the grassy looking foliage afterwards even if the blooms had been mauled by the weather. You might dig down a bit and see if the corms are still there. If so, they should be fine and should bloom again next spring.
