Ferrell Secakuku remembers the ancient farming rites of his Hopi people but saw them replaced by a cash economy. Sheep rancher Joe Manterola recalls watching hard scrabble farms on what is now tree-studded grassland on Garland Prairie. Navajo Rose Gishie once saw freshly dug holes fill with clean, drinkable water where none rises today. All over northern Arizona, people have seen the landscapes change, and livelihoods with them. In this remarkable book they share their stories. Thirteen narrativesÑfrom ranchers, foresters, scientists, Native American farmers, and othersÑtell how northern Arizona landscapes and livelihoods reflect rapid social and environmental change. The twentieth century saw huge changes as ArizonaÕs human population swelled and vacation-home developments arose in the backcountry. Riparian areas dried up, cattle ranching declined, and some wildlife species vanished while others thrived. The people whose words are preserved here have watched it all happen. The book is a product of Northern Arizona UniversityÕs Ecological Oral Histories project, which has been collecting remembrances of long-time area residents who have observed changes to the land from the 1930s to the present day. It carves a wide swath, from the Arizona Strip to the Mogollon Rim, from valleys near Prescott to the New Mexico line. It takes readers to the Bar Heart Ranch north of Williams and to the Doy Reidhead Ranch southeast of Holbrook, to the forests of Flagstaff and the mesas of Indian country. Enhanced with more than fifty illustrations, this book brings environmental change down to earth by allowing us to see it through the eyes of those whose lives it has directly touched. What Has Passed and What Remains is a window on the past that carries important lessons for the future.
