The West gate is probably the most active. I left at 6:30 and saw the sunrise and this herd of elk with the first 10 minutes. Today I went south in the park towards Old Faithfull. Something you do not see everyday is a
wolf pack. This Bison was by himself but with my long lens he looked like he was right next to me. The trumpeter swan was relaxing in the lake.
Videos after Old Faithful, so if you click through the pictures you will miss the videos.

The wolves in Yellowstone were on the move today. This pack was by the West entrance, but no telling how far they travel.
