Spring is in the air

Click for larger map.

As the snow starts to melt, the roads in Yellowstone National Park will be plowed and cleared in readiness for letting cars and trucks back in. (Of course, the road from the North Entrance at Gardiner, Montana, through the park to Cooke City, Montana is open all year. But notice that travel east of Cooke City via the Beartooth Highway is not possible from late fall to late spring.) Here are dates to use in your planning this spring.
