I'm actually very jealous of your big dump! A good three footer all in one shot doesn't happen all that often anywhere. Being a skier in a small ski town that's cause to celebrate. Nobody goes to work, everyone calls in sick and hits the slopes. We have a good amount of snow this year but it's all come as frequent little 3-4" teaser snowfalls, not even one big rippin dump yet this season.
I've actually had more problems with the conifers in the past though,with their foliage still on they can catch the snow more than leafless deciduous that alow the snow to filter through more. The conifers can get some pretty heavy unsupported hats of snow. My experience so far anyways but I don't have any large, well ramified decid trees.
I'm always thinking snow load when I pack trees away, adding support struts here and there. Supporting sensitive branches with rigid deadwood of adjacent trees. Keeping trees away from flexible branches of larger trees that might squash them, far enough from the house to not get clobbered by roofalanches etc....
Check out the tree well under this juniper, the hole goes right down to the mulch and the tree is holding all the weight. This tree is strong and unstyled and can take it but some of them need protection.
Must have been an exciting snow event for a lot of people down there!
