We Are Entering Gardiner, MT Which Is Located In the Valley Of The Yellowstone River.
….At Left In the Distance, Note Huge Ceremonial Arch. This "Arch Of Triumph" Celebrates Establishment of Yellowstone National Park,
….AND, No Doubt, Celebrates The Tourist Industry That Followed!!.
……The Super STEEP Road We Have Been Traveling On, At One Time Was the ONLY Entrance To Yellowstone National Park.

…. “We decide to stay here for the night.“

Gardiner, MT. Our highway US-89 Enters Gardiner, MT which is nestelled in the Yellowstone River Valley, beside the Yellowstone River: And here the Gardiner River ends by flowing into the Yellowstone River.
….After Gardner, MT, the ZMM Route will fairly closely follow the Yellowstone River, Northwest then North all the way to Livingston, MT. Where-upon it re-joins I-94 to go WEST over The Bridger Mountains via Bozeman Pass. ((Please note => I-94 going EAST essentially follows the Yellowstone River Valley, per next sentence =>
….However, due to The Bridger Mountains and The Big Belt Mountains, The Yellowstone River is forced to go EAST to Miles City, MT and thence to Glendive, MT, near the Montana-North Dakota Border, and ~there flow into the Missouri River.
