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.
Complacent pollen records associated with both extinct fauna and archaeological remains argues that Southwest has been semi-arid throughout Late- and Post-Pleistocene.
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.
This study of 23 pollen samples allows recognition of a sequence of ecosystem changes occurring in central New Mexico between A.D. 1280 and 1400 and also in the 1650 - 1750 period. It also discusses the effects of such changes on aboriginal maize agriculture. Draft of the report included in Archaeological Excavations at Pueblo del Encierro.
Unpublished report, 1964
Pilot study of 3 pollen samples allows vegetation pattern reconstruction for period of occupation and suggests successful maize farming required water control technology.
