Frommer's national parks of the American West

A Denver-based freelance writer, Eric Peterson has contributed to numerous Frommer's guides covering the American West, and has written Frommer's Montana & Wyoming, Frommer's Colorado, Frommer's Yellowstone & Grand Teton National Parks, and Ramble: A Field Guide to the U.S.A. Peterson also writes about travel and other topics for such publications as ColoradoBiz, Delta Sky, and the New York Daily News. In his free time, he's an avid camper and hiker, a lifelong Broncos fan, and a part-time rock star (at least in the eyes of his niece Olivia and nephews Mitch and Sam).

Jack Olson, a longtime resident of Denver, wanders the Rockies and the entire country as a freelance photographer and writer. He writes travel articles and supplies photographs for AAA magazines, and his photos have been seen in such publications as Backpacker, Audubon, Sierra, and National Geographic Books.

Shane Christensen has written extensively for Frommer's, including guides to Latin America, Europe, and the United States. Originally from California, he knows the American Southwest well and returns each year to the Grand Canyon to explore its wonders and ensure the accuracy of this guide. Shane has also held a variety of diplomatic assignments with the U.S. Department of State, and he is currently a research scholar and faculty advisor at Columbia University.
