Santa Fe : Museum of New Mexico Press, 2020. pages cm. txt rdacontent n rdamedia nc rdacarrier "About 1.25 million years ago, a spectacular volcanic eruption created the 13-mile wide circular depression now known as the Valles Caldera, located in northern New Mexico. This revised & expanded edition marks the twentieth anniversary of the Valles Caldera Preservation Act, a visionary piece of legislation that transferred to the public domain a privately owned ranch (signed in 2000 by President Bill Clinton). The preserve was assigned to a board of citizens appointed by the president to manage it as a self-sustaining preserve. The experiment in semi-private land management ended in 2014 as the Valles Caldera was legislatively reassigned to the National Park Service. First published in 2006, this book tells the natural and human story of the Valles Caldera and details the establishment of it as a national preserve to be enjoyed by all. William deBuys, former chair of trustees for the preserve from its creation through 2005, has written a new essay that brings us up-to-date on policy and management changes, including the end of the fourteen year experiment and transfer to the National Park Service. DeBuys discusses ongoing ownership claims by indigenous peoples with cultural and spiritual connections to the land and urges the need for the federal managers to allow access and use by American Indian Pueblos. Don J. Usner contributes new photography, including a black-and-white portfolio, documenting changes to the landscape due to environmental factors. The Las Conchas fire in 2011 had the most impact, burning 30,000 acres of the preserve. Usner contributes a moving new essay that evokes his personal relationship with the caldera-a place he has visited since boyhood"-- Provided by publisher. 20240522. Usner, Don J., author.
