This Is Dinosaur was first published in 1955, in the midst of a bitter controversy over the proposed construction of dams at Echo Park. The outcome of the controversy--a congressional vote to prohibit the dams--"set in brass the principle that any part of the national park system should be immune from any sort of intrusion and damage," wrote Wallace Stegner in the 1985 edition of the book. Reprinted with new color photographs, This Is Dinosaur still stands as a classic introduction to the historic, scenic, archeological, and biological resources of the Monument by an impressive array of writers. Contains the following essays: ·"The Marks of Human Passage" by Wallace Stegner ·"Geological Exhibit" by Eliot Backwelder ·"The Natural World of Dinosaur" by Olaus Murie and Joseph W. Penfold ·"The Ancients of the Canyons" by Robert Lister ·"Fast Water" by Otis "Dock" Marston ·"A Short Look at Eden" by David Bradley ·"The National Park Idea" by Alfred A. Knopf
