This book makes you the tour guide for your group! Janet Chapple shares her tips to pack for your trip, spot wildlife, see the best views, catch geyser eruptions, stay safe, and escape the crowds. The author's passion for the park, which began when her parents worked at Old Faithful Inn in the early twentieth century, shines throughout. Whether you want to hike in the geyser basins and forests, drive the mountain passes, ride horseback, or take a boat out on the lake, the mile-by-mile road logs prepare you. The description is enlivened by entertaining historical anecdotes. This sixth edition, fully updated for 2020 by editor Beth Chapple and geologist Jo-Ann Sherwin, includes which geysers and hot springs are active, the new overlooks at Grand Prismatic Spring and the south rim of the canyon, a new time line of the geology, and explanations of the geological forces like lava flows and the Yellowstone hot spot. The book is in full color with 38 new and revised maps. Charts of the facilities and a field guide to the wildlife and wildflowers round out this comprehensive guide to America's first national park. After the first edition won Gold in the Travel Guides category in ForeWord Magazine's 2002 Book of the Year Awards, later editions won Silver in the IBPA Benjamin Franklin Awards in 2010 and 2018.
