The Grand Tetons National Park is very large, more than 480 square miles. But the entrance/exit gates don't match the actual boundaries. We'd been driving along the west road all morning, inside the gates. We reached the south end and exited the gates, but didn't exit the park.
John and Margaret Cunningham established the Bar Flying U Ranch here in the 1880s. The couple managed to remain profitable through drought and falling livestock prices, but they eventually succumbed in 1928. They sold out to the Snake River Land Company (the dummy corporation set up by John D. Rockefeller to unite Jackson Hole with Grand Tetons National Park).
