We actually had our honeymoon south of Yellowstone in front of the Tetons, 14 years ago this month. Stayed in a cabin just in front of the Teton range.
Your 2nd photo of the eagle looks like it was just outside our cabin. We would see a lone eagle come down and perch on a tree just like that every morning.
Great time to visit the area. Few crowds, snowshoeing, winter elk refuge, etc.
Thanks for the photos.
