ABSTRACT: This book is a response to the USGS’s call for a research design that could be used as a framework for prioritizing cultural resources in the Colorado River ecosystem below Glen Canyon Dam. Changing River includes summaries of current environmental conditions and previous research and brings together diverse archaeological opinions about Grand Canyon’s human story. It then presents a theoretical basis for using a landscape approach to organize future research efforts in the canyon. The research presented here explores the geophysical, paleoclimatic, and biological parameters that have shaped the canyon landscape and influenced choices made by humans as they attempted to adapt to this ecosystem. It then focuses on the distribution of cultural materials and patterns using several archaeological approaches, and investigates natural and cultural realms as mutually reinforcing and interacting components of an integrated ecosystem to which humans have applied meaning and value over time.

ABSTRACT: As called for in its operational plan, the Cultural Program of the Grand Canyon Monitoring and Research Center convened a Protocol Evaluation Panel (PEP). The Bureau of Reclamation co-sponsored this PEP. In 1994, a Programmatic Agreement (PA) was developed by the Advisory Council on Historic Preservation with the following parties: Bureau of Reclamation, National Park Service, Arizona State Historic Preservation Office, Havasupai Tribe, Hopi Tribe, Hualapai Tribe, Kaibab Paiute Tribe, Navajo Nation, San Juan Southern Paiute Tribe, Shivwits Paiute Tribe, and Zuni Pueblo. The Havasupai Tribe and the San Juan Southern Paiute Tribe have not signed the PA as of this report’s completion. The PEP was structured to address four topical areas: monitoring and compliance, archaeology, Native American issues, and geomorphology. Overall recommendations were developed by the full panel, based on the results of subpanel reports on the four topical areas.

ABSTRACT: This is the original cultural resources compliance document that was prepared in conjunction with the 1996 Environmental Impact Statement on the operations of Glen Canyon Dam. Broadly, it stipulated that cultural resources along the Colorado River corridor would be identified and evaluated for National Register eligibility, a Monitoring and Remedial Action Plan would be developed that would guide future monitoring activities and remedial actions necessary to address any adverse effects to historic properties that was identified through the monitoring. Finally, a Historic Preservation Plan was to be developed that would guide the long-term management of the historic properties under the 1994 PA. This document would incorporate all of the previous actions.
