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.
