Like pages in a book, the layers of sedimentary rock that are exposed on the Colorado Plateau tell us much about the diversity of environments that have come and gone over a period of hundreds of millions of years. This region is recognized as one of the finest earth science laboratories in the world. New discoveries and analyses of the fossil record here are answering questions, solving mysteries, and making connections that help us understand the history of life worldwide. CHRISTA SADLER, author of the Geology pages, is a geologist, guide, and educator from Flagstaff, Arizona. She has worked on rivers throughout the Southwest and Alaska, and in Ecuador, and has spent the last 14 years as a guide and trip leader on the Colorado River in Grand Canyon. In addition to occasionally teaching introductory geology and paleontology at Northern Arizona University in Flagstaff, she works as a geology instructor for the Grand Canyon Field Institute, and runs geology programs for park service personnel at Grand Canyon National Park. She is currently working on two books, one about the fossil history of the Colorado Plateau and its national parks, the other a sequel to her first anthology of Colorado River stories.
The National Park Service, in cooperation with the Museum of Northern Arizona, is excavating nine archeological sites along the Colorado River in Grand Canyon National Park as part of a five-year project. These are the first major excavations along the Colorado River in Grand Canyon in nearly 40 years. Archeologist Lisa Leap, the projects co-director, received her MA in archeology from Northern Arizona University in 1992. Leap will share new insights into Grand Canyons prehistory that have been gained through this exciting project.
On the 140th anniversary of Major John Wesley Powell's pioneering 1869 trip down the Green and Colorado rivers, researchers are still discovering new information about Powell and his life. Powell has most often been described as a soldier, explorer, adventurer, and scientist. But he was also a consummate government bureaucrat and a visionary for his recognition of the West as the "Arid Lands." Join Northern Arizona University Special Collections librarian Richard Quartaroli to hear about the latest research into the wild and mild worlds of John Wesley Powell.
Lori Romes book for children, The Adventures of Salt and Soap at Grand Canyon, is the true story of two puppies that wandered into the Grand Canyon and experienced great adventures in the grandest of all canyons—multiple rim-to-river hikes, a river trip on the mighty Colorado and a helicopter ride out of the canyons depths—while ultimately snuggling their way into park rangers and visitors hearts.
Join Lori, the park ranger who adopted Salt and Soap, as she shares their unique and inspirational story.
Martha Hahn highlights some of Grand Canyon National Parks current projects, giving a behind-the-scenes look at the role the Division of Science and Resource Management plays in preserving and protecting Grand Canyon.
Authors and veteran adventurers Michael Ghiglieri and Tom Myers wrote a book a decade ago titled "Over the Edge: Death in Grand Canyon" that has since become a bestseller. "Over the Edge" chronicles how 550 souls were lost to the Grand Canyon since the time of John Wesley Powell's navigation of the then-untamed Colorado River. Now, 10 years later, Ghiglieri and Myers have new gripping tales of both death and survival in the canyon, as well as a few lessons that may prove to be life-saving.
