In 1891, the Northern Pacific Railway began erecting a grand hotel overlooking magnificent Yellowstone Lake to welcome visitors to the magical western park dubbed "Wonderland"-where geysers erupt, waterfalls plunge, and wild animals roam. The oldest hotel in America's national park system has endured as a destination beloved by millions. Michelle Trappen's photo-packed book celebrates the hotel's 125th birthday and tells the remarkable story of a true survivor-the Grand Lady of the Lake.
