Most of the low level snow in Yellowstone melted last week with many days of 50+ in the park. So when a spring storm sweeps across sothwest Montana it is a good time to head into Yellowstone to see the effects and action that snow has on springtime in the park. I love the way the bison ride out all the adversity that winter (and spring) can throw at them. Nothing fazes a bison! Lots of Bluebirda and other spring arrivals of the avian sort. And the wolves love to hunt with the arrival of any snow whatsoever.
