Located in Yellowstone, 2.5 miles south of Gardiner, Montana, and 2.5 miles north of Mammoth Village, the 45th Parallel marks the halfway point between the equator and the North pole, crosses through Yellowstone National Park and a sign delineating its location along US-89. This is a great free photo opportunity!
