During the U.S. 89 project, 41 prehistoric sites located approximately 30 km (48 miles) north of Flagstaff, Arizona, were investigated. All sites were on Coconino National Forest (CNF) land, specifically the Peaks Ranger District. The project was conducted by Desert Archaeology, Inc., personnel for the Arizona Department of Transportation (ADOT) prior to widening and improvement of 26.7 km (16.6 miles) of U.S. 89, between the southern boundary of Wupatki National Monument in the north, and the town of Fernwood in the south. Archaeological fieldwork occurred over two primary field seasons in 1997 and 1998, with a very brief field season in 1999. A total of almost 12 person-years of labor was expended during fieldwork. The analyses of environmental data recovered during the U.S. 89 project are presented in this volume.

The U.S. 89 Archaeological Project investigated 41 prehistoric sites located approximately 30 km north of Flagstaff, Arizona. All sites were on Coconino National Forest (CNF) land.

Archaeological fieldwork occurred over two primary field seasons in 1997 and 1998, with a very brief field season in 1999. A total of almost 12 person-years of labor was expended on the fieldwork. The U.S. 89 project area crosses diverse environmental zones, ranging from juniper-sage grasslands in the north at approximately 5,700 ft (1,737 m) asl, to ponderosa pine forests at over 7,200 ft (2,195 m) asl in the south. Mixed pinyon pine and juniper woodlands comprise the middle elevations. Five elevation zones were defined, using increments of 500 ft as a proxy for changes in precipitation, temperature, and vegetation. All project area sites are also within 25 km of Sunset Crater Volcano, with the closest sites only 5-6 km away. Sunset Crater erupted for a few years sometime between A.D. 1050 and 1125. Basalt lava from the eruption covered an area of approximately 8 km2, while another 2,300 km2 was covered by cinder and ash deposits. Sunset Crater cinders were found on all project area sites. An isopach map of cinder depth constructed for this project indicates that, minimally, the U.S. 89 sites were covered with from 5-50 cm of volcanic material, which had a significant impact on prehistoric settlement, subsistence, and economic systems. Prehistoric adaptation to environmental variability and to the Sunset Crater eruption were primary research themes. The results of the U.S. 89 investigations are presented in a series of anthropological papers: Anthropological Papers No. 30, Part I and Part 2, contain background information on the project and descriptions of the 41 investigated sites.Part 1 includes the two sites in Elevation Zone 1 (5,700-6,199 ft [1,737-1,889 m] asl) and 11 sites in Elevation Zone 2 (6,200-6,699 ft [1,890-2,042 m] asl), the lower elevation zones in the northern half of the project area.

Additionally, all project area sites are within 25 km of Sunset Crater, with the closest sites only 5-6 km west of the volcano. Sunset Crater erupted for a very short period (months to a few years) sometime between A.D. 1050 and 1125. Basalt lava from the eruption covered an area of approximately 8 km2, while another 2,300 km2 was covered by cinder and ash deposits. Sunset Crater cinders were found on all project area sites.

Prehistoric adaptation to environmental variability, as well as to the Sunset Crater eruption, were primary research themes. This volume presents the analyses of the non-ceramic artifacts from the 41 investigated sites. These artifacts comprise approximately 16.5 percent of the 98,329 total recovered artifacts: 15,610 pieces of flaked stone, 1,163 pieces of ground stone, 96 bone tools, 70 pieces of shell, and 237 miscellaneous artifacts, which include stone beads, jewelry, and pieces of pigment. Additionally, 3,493 pieces of unworked animal bone were also recovered.
