Received some interesting communication about this. Several trails are closed for grooming; they did not want to groom this morning due to the timing of the frontal passage, which in order to open trails would have forced to groom before the freeze resulting in extremely packed conditions. Instead, they chose to keep the trails closed, let them freeze solid and then reopen after they've been groomed - plus some snowmaking. I actually think decisions like that are what makes this mountain so much better; I've seen plenty of times groom at Cannon with temperature in the 40s ahead of a cold front, and then the next day those trails were unskiable. This allows them to do it right.
