Yellowstone National Park, Northern Entrance. The North Entrance is located in Gardiner, Montana, 50 miles south of Livingston, Montana at Interstate 90. The closest airport is Bozeman, Montana, approximately 85 miles from the entrance.
I collected two samples, one just inside the northern entrance on a curve in the road where Robin and I found two buffalo walking in the middle of the road. The other at the Roosevelt Arch, completed on August 15, 1903, the massive stone structure offers a glimpse into the park’s early years.
