Whiteout! Snow Mountain by the numbers

Launched four years ago, Snow Mountain, the attraction in which guests tube down Stone Mountain Park's sloping Memorial Lawn on a blanket of machine-made white stuff, is open ahead of Christmas for only the second time.

Even on days when the Atlanta weather is more like spring than winter, it offers another option for the annual what-to-do-with-those-holiday-visitors quandary. Here, we take a by-the-numbers look at this extra-large operation.
