I would say that it's based on Wind/Metal. I could be be wrong but, if it was ICE, wouldn't it inflict snowman status on other areas besides Snowy Mountains? It probably picks what is present on the environment - e.g. Wind attacks on snowy mountains = ice; wind attacks on jungle/desert = just wind (maybe some water or dust)
