The mere words "opening day" carry so much importance, and even lore, for a ski resort.
After all, that's when the big ribbon is cut with the pair of big scissors, and that's when the slopes open for another multi-month run, and that's when all of the wintry festivals begin to take shape, like so many snowflakes drifting in from parts unknown.
But there's another milestone on the calendar for upper-elevation destinations, and it involves when the first snow occurs.
That moment might happen months before opening day, as it did for Mammoth Mountain in 2017, when snow fell at the very end of summer, or it might nestle up a bit closer to when the schussing is set to start.
