A lifetime love affair with Yellowstone National Park has developed into an obsession. Yellowstone has everything: incredible thermal features, mountains, lakes, rushing streams and lovely waterfalls, unusual wildlife, gorgeous wildflowers—I could go on and on with this list, but instead I took on a second career researching and writing books about this unique place. My latest book is a historical anthology of very early writings about Yellowstone, with the title "Through Early Yellowstone: Adventuring by Bicycle, Covered Wagon, Foot, Horseback, and Skis." The book's centerpiece consists of nearly thirty delightful watercolor sketches by one of the authors (a horseback tourist), Thomas H. Thomas, who visited the park in 1884. Starting as an effort to update the old-time best guide to Yellowstone Park (1890–1966) by the Haynes father and son, I began researching in 1995 for my best-selling guidebook, "Yellowstone Treasures." I formed my publishing company, Granite Peak Publications, with the generous help of my daughters five years later. Daughter Beth and I have now turned out four editions of the guidebook and plan to produce others. Since 2014, Beth is GPP's publisher, as well as editor and webmaster. From information in "Yellowstone Treasures," I've also put together a very portable booklet, "Visiting Geyserland." It describes what you'll see as you visit the ten easily accessible thermal areas in the park. Another project, with colleague Suzanne Cane, was translating "Yellowstone, Land of Wonders," published in 2013 by the University of Nebraska Press. This is an entertaining and well-written travelogue published in 1888 by Belgian judge Jules Leclercq, who traveled across the U.S. by train to visit Yellowstone. Brought up in Billings, Montana, I attended Stanford and graduated from the U. of Southern California, with a couple of quarters at U. of Washington. I married Bill Chapple, with whom I had three daughters. My education and first career were in cello performance and teaching, and I earned a master's degree in cello performance at Indiana University after Bill died of cancer. We lived in Rhode Island, and I married geochemist Bruno Giletti there in 1984. We now enjoy our apartment overlooking Lake Merritt in Oakland, California.
