A model is proposed that incorporates cultural and environmental aspects of human response to natural disasters. The 11 th century eruption of Sunset Crater volcano in northern Arizona is used as a case study in which the archaeological record and dendrochronological and geomorphological evidence are combined to characterize the nature of the human response. The model predicts that the population at Sunset Crater would have been pressured to move, or to move and make cultural or technological adaptations following the eruption. The model has utility in diverse conditions and can be used to interpret archaeological remains and facilitate modern disaster response.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>32</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Wright, William Edward</style></author></authors><tertiary-authors><author><style face="normal" font="default" size="100%">Dean, J.</style></author></tertiary-authors></contributors><titles><title><style face="normal" font="default" size="100%">Tsegi Canyon Cliff Ruin Beam Coring Project: A Dendrochronological Analysis of Six Sites in the Tsegi Canyon Complex, Northeastern Arizona</style></title><secondary-title><style face="normal" font="default" size="100%">Anthropology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Archaeology</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1997</style></year></dates><publisher><style face="normal" font="default" size="100%">University of Arizona</style></publisher><volume><style face="normal" font="default" size="100%">MA</style></volume><language><style face="normal" font="default" size="100%">eng</style></language></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>6</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Robinson, William J.</style></author><author><style face="normal" font="default" size="100%">Ronald H.

K. Bailey, sp. Nov.) in the White Mountains of east-central California where living trees reach ages in excess of 4,000 years. The focus of this report relates to the support by the Geology and Anthropology sections in the National Science Foundation under grant EAR-8018687 for the period 1 April 1981 to 31 October 1984 with the assistance of the Department of Energy contract no. DE-AC02-81EV10680 covering the period 1 May 1981 to 31 October 1982.&lt;/p&gt;&lt;p&gt;A summary of this research was recently published in &lt;u&gt;Radiocarbon &lt;/u&gt;(Ferguson and Graybill 1983). In most cases various facets of the work were related to projects sponsored by all agencies. Therefore the full range of activities during that period is described herein. The primary project goals were:&lt;/p&gt;&lt;ol&gt;&lt;li&gt;To extend the bristlecone pine chronology from the White Mountains of California beyond 6700 B.C. and strengthen it by incorporating additional specimens.&lt;/li&gt;&lt;li&gt;To develop bristlecone pine chronologies in new areas for applications in archaeology, isotopic studies, and other earth sciences.&lt;/li&gt;&lt;li&gt;To furnish dendrochronologically dated wood to researchers engaged in the study of past variations in carbon isotopes and climate.&lt;/li&gt;&lt;/ol&gt;</style></abstract></record><record><source-app

style=&quot;margin-left:.5in;&quot;&gt;The interpretation of approximately 5715 dated tree-ring specimens from about 342 archaeological sites in the American Southwest is the basis for &amp;ldquo;dating&amp;rdquo; the pottery types found in association. The time involved spans the period from the introduction of fired ceramics to the Spanish Entrada, approximately A.D. 1550.&lt;/p&gt;&lt;p style=&quot;margin-left:.5in;&quot;&gt;The provenience and site situation information for both the dated tree-ring specimens and the associated pottery is tabulated for each site and site-area which has tree-ring dates, except when these data are accessible in the literature.&lt;/p&gt;&lt;p style=&quot;margin-left:.5in;&quot;&gt;Criteria for establishing the validity of the association and provenience of the tree-ring specimens and the pottery are formulated. The interpretation and evaluation of the validity of these dates and associations is the basis for &amp;ldquo;dating&amp;rdquo; the various pottery types. The occurrence of pottery in &amp;ldquo;Indigenous&amp;rdquo; and &amp;ldquo;Trade&amp;rdquo; situation is presented separately; the pottery types in these categories are dated separately, in so far as possible, and then evaluated in terms of total distribution and context. Approximately 325 pottery types, varieties, and ceramic categories are dated on the basis of archaeological associations with tree-ring specimens. The data presented do not change the gross time placements of previous workers, but they do (1) refine some pottery dates, (2) reject others, and (3) give differing validity to additional ceramic dates.&lt;/p&gt;&lt;p style=&quot;margin-left:.5in;&quot;&gt;The concept of &amp;ldquo;pottery type&amp;rdquo; is used as the analytical unit for dating Southwestern ceramics. The concept of &amp;ldquo;Ceramic Style&amp;rdquo; represents synthesis at a higher level of abstraction and does not lend itself to dating based on tree-ring material.&lt;/p&gt;&lt;p style=&quot;margin-left:.5in;&quot;&gt;A progressive increase in the amount and range of traded pottery is noted through time. The increase in the distribution of various pottery types after about A.D. 1250 is also accompanied by an increase in attempts to make local copies of certain pottery types obtained by trade.&lt;/p&gt;&lt;p style=&quot;margin-left:.5in;&quot;&gt;Decorated pottery types which occur as trade products tend to persist in later archaeological contexts and this situation is discussed as the &amp;ldquo;Lasting Phenomenon of Traded Ceramics.&amp;rdquo;&lt;/p&gt;&lt;p style=&quot;margin-left:.5in;&quot;&gt;Southwestern pottery is distributed in prehistoric times on the basis of hand-to-hand or person-to-person contact and although the amount of trade and the spatial dispersal increase in time, particularly after 1250, this trade never reaches the same degree of institutionalization that is seen in Mesoamerica.&amp;nbsp;
