Since Sun Valley was, along with southern Utah, the crown jewel of Union Pacific’s tourist destinations, naturally it rated its own edition in the railroad’s expanded line of tourist guides. Not only was UP the only railroad that accessed Sun Valley, as a largely winter destination it helped to balance out the summer tourist season. The railroad also had reason to be proud of the fact that its invention of the chairlift, which was soon imitated by ski resorts all over the West, helped generate the post-war ski boom.
So it is not surprising that this booklet is as long as its peers for California, the Pacific Northwest, Yellowstone, and Zion, and longer than the 1940s Colorado booklet. Like these booklets, but unlike the Dude Ranch booklet, the Sun Valley booklet has a fold-out map on the inside back cover. Inside are 32 color and 13 black-and-white photos showing Union Pacific’s own lodges and ski slopes.
