The beautifully constructed archway was built at the north entrance, which was the first major entrance for Yellowstone.
Construction of the arch began on February 19, 1903, and was completed on August 15, 1903, at a cost of around $10,000.
This shot came out perfectly - much better than mine :) (mine slightly tilted and not enough room to straighten) the darker skies at that hour were perfect - even the puddle of rain made the grass sharper. Nicely balanced.
