You knew the show at the Denver Central Library was serious simply by noting the word count of the title: From Nordenskiold to Nusbaum: Archaeology, Photography and Tourism in the Early Years of Mesa Verde National Park. Whew, seventeen! The Nordenskiold part refers to Gustaf Nordenskiold, who explored Mesa Verde in 1891, and the Nusbaum part addresses Jesse Logan Nusbaum, who became an early superintendent of Mesa Verde National Park. Their photos were supplemented with images by William Henry Jackson, George Beam, Laura Gilpin and others. The exhibit was curated by the Colorado Historical Society's Thomas Carr and the library's Trina Purcell, who together selected some of the best pieces from their respective institutions to pull off this knockout of a show.
