All Yellowstone Park roads except the all-weather road between Gardiner and Cooke City in the northern part of the park will close Monday, November 3, 2014, at 8:00 am. And just in time, too: On Sunday and Monday, October 26 and 27, there was up to one foot of snow in some places and a few drivers were stranded until snowplows could reach them. A dusting of snow remained at Old Faithful in late afternoon on Tuesday (10/28), as I just saw on the Old Faithful streaming webcam.
December 15th will be the day most roads will be ready for snowcoaches and snowmobiles.
