“Outdoorsman and author Jeff Alt has "hit another home run" with the newest addition to his "The Adventures of Bubba Jones" book series. In previous adventure stories, Alt's characters "Bubba" Jones and sister Jenny "Hug-A-Bug" have taken readers on magical visits to Great Smoky Mountains National Park, Shenandoah National Park, and Acadia, and now his adventurous explorers visit one of the most iconic of all our national parks, Grand Canyon. In Alt's new adventure, readers can feel the desert wind blowing off the Coconino Sandstone, feel the swish and power of the Colorado River as it roars through the Inner Gorge, feel the presence and mystery of the Puebloans and the "ancient ones" who lived in the canyon in prehistory, and discover the grandiose drama of geology and erosion that created this wonder of the world. "The Adventures of Bubba Jones--Time Traveling Through Grand Canyon National Park" follows in the footsteps of Alt's earlier books and will provide young readers with a magical adventure in the one and only "Grand Canyon."
