Summarizes the attached resource reports that have been submitted so far to help develop the SDCP within the watershed planning area of the Altar Valley. This initial presentation of resource information is intended to both educate and serve as an invitation to greater participation in crafting the SDCP.

Arivaca, located on the southern border of Pima County, is one of the few remaining riparian areas in southern Arizona. This report presents collected data, shows how the Arivaca area relates to the SDCP, and makes recommendations on how the plan could address pressing groundwater issues in the Arivaca Valley.

A companion to the "Importance of Conserving Resources in the CIenega Creek Watershed" document and provides a focus on Altar Valley. This report includes detailed investigations into the historic conditions of the watershed, current rangeland conditions of biotic communities, and the environmental impact of a potential floodplain project.

Draft of report published in A.H. Schroeder, 1965, Anthropological Papers of the Department of Anthropology, University of Utah, Misc. Coll. Papers 75; 10: 85-110. Pilot study of 3 pollen samples suggests pollen chronology developed for Northern Arizona and New Mexico portions of the Colorado Plateau not applicable to SE Utah.

Palynological study of 18 samples, including 5 associated with Archaic Period radiocarbon dates and 1 associated with Fremont Culture artifacts, identifies a pollen sequence for the site. The inferred paleoclimatic sequence fully agrees with dated sequences from central New Mexico and the Llano Estacado.
