In the western high country, it can snow any month of the year. We visited Glacier NP many years ago after a good snow storm. The national news reported Glacier closed (it was for a few hours), so the crowds went elsewhere. It was great to have the park relatively unpopulated.takesiteasy said:Sorry, drought or no, I do not like seeing snow in July. We only have 3 reliable snow-free months here and July is one of them.
