While Union Pacific rails reached Yellowstone National Park, it had to share access to that park with the Northern Pacific and several other railroads. But UP was the only railroad to reach Zion and Bryce Canyon, and it built lodges in both parks as well as on the North Rim of the Grand Canyon. This menu from March, 1971, features Zion.
The menu itself is identical to yesterday’s Mt. Hood menu. In addition to dinners, the menu offers bottles “for two” of California red or white wine for $1.25 a bottle–a little over $7 in today’s money.
