This book is my homage to the artist Thomas Moran, and his superb work in Yellowstone. It’s an enhanced iBook, available at the iTunes Store, and viewable only on an iPad or a Mac running the iBooks app. In my opinion, there’s no better way to see Moran’s work — except in person — than on the vivid color monitor of a retina display. But you’d have to do a lot of traveling to stand in front of all the images I’ve packed into this portfolio. The book also includes some photographs by William Henry Jackson, who worked beside Moran during their magical first experience with Yellowstone as members of the 1871 Hayden Survey.
