As Snowolf touched on you need specific type of trees to form tree wells. In Aus we don't get tree wells at all. Mainly due to the reason we don't get the volume of snow as they do in the PNW BUT even if we did, tree wells wouldn't from with our alpine gum trees. They are the complete wrong shape and they don't spread out at the bottom and taper at the top.
