I've been digging around for a couple of days and not even a hint of an official closing date so far. There is a reported snow depth of only 12 inches in the meadows but it's unlikely to go anywhere with the freezing temps. In fact the Mono Lake crew have been praying to the snow gods in the wake of another dry season. November 19th looks to be the last time it was open to traffic but we will have to wait and see.
