Dating the Methuselah Walk Bristlecone Pine Floating Chronologies
Two floating, ring-width chronologies predate the long bristlecone pine (Pinus longaeva) absolutely-dated, ring-width chronology from the Methuselah Walk (MWK) site in the White Mountains of California. The two non-overlapping floating chronologies were derived from samples that crossdate internally but are temporally unconnected to each other and to the nearly 9000-year, ring-width sequence that is crossdated to the calendar year. We used radioc…
The Role of Climate in Early Spanish–Native American Interactions in the US Southwest
Fine-scale modeling of bristlecone pine treeline position in the Great Basin, USA
Great Basin bristlecone pine (Pinus longaeva) and foxtail pine (Pinus balfouriana) are valuable paleoclimate resources due to their longevity and climatic sensitivity of their annually-resolved rings. Treeline research has shown that growing season temperatures limit tree growth at and just below the upper treeline. In the Great Basin, the presence of precisely dated remnant wood above modern treeline shows that the treeline ecotone shifts at cen…
Cluster analysis and topoclimate modeling to examine bristlecone pine tree-ring growth signals in the Great Basin, USA
Tree rings have long been used to make inferences about the environmental factors that influence tree growth. Great Basin bristlecone pine is a long-lived species and valuable dendroclimatic resource, but often with mixed growth signals; in many cases, not all trees at one location are limited by the same environmental variable. Past work has identified an elevational threshold below the upper treeline above which trees are limited by temperature…
Search for Annual 14 C Excursions in the Past
Two radiocarbon excursions (AD 774–775 and AD 993–994) occurred due to an increase of incoming cosmic rays on a short timescale. The most plausible cause of these events is considered to be extreme solar proton events (SPE). It is possible that there are other annual 14 C excursions in the past that have yet to be confirmed. In order to detect more of these events, we measured the 14 C contents in bristlecone pine tree-ring samples during the per…
Timing and climate forcing of volcanic eruptions for the past 2,500 years
Changing climate response in near-treeline bristlecone pine with elevation and aspect
In the White Mountains of California, eight bristlecone pine (Pinus longaeva) tree-ring width chronologies were developed from trees at upper treeline and just below upper treeline along North- and South-facing elevational transects from treeline to ~90 m below. There is evidence for a climate-response threshold between approximately 60–80 vertical m below treeline, above which trees have shown a positive growth-response to temperature and below …
An annually resolved bristlecone pine carbon isotope chronology for the last millennium
We present the first near millennium-length, annually resolved stable isotope record from bristlecone pines ( Pinus longaeva , D.K Bailey). The carbon isotope ratios from the cellulose of seven trees from the White Mountains of California, corrected for anthropogenic changes in atmospheric chemistry, are used to reconstruct growing season (June through August) precipitation back to AD 1085. Extremely negative isotope results are strongly correlat…
An Assessment of the Dendroclimatic Potential of Three Conifer Species in Northern Minnesota
Ring-width chronologies from Pinus resinosa Ait., Pinus strobus L., and Thuja occidentalis L. were developed in two areas of the Boundary Waters Canoe Area Wilderness to assess their growth-climate response and their potential for developing reconstructions of climate. New red pine chronologies were combined with existing chronologies to extend the ring-width record both into the past and into the present. Ring-width response to climate, assessed…
Assessing the Importance of Past Human Behavior in Dendroarchaeological Research
Dendroarchaeological samples can contain three kinds of information: chronological, behavioral, and environmental. The decisions of past people regarding species selection, beam size, procurement and modification techniques, deadwood use, and stockpiling are the most critical factors influencing an archaeological date distribution. Using dendrochronological samples from prehistoric and historic period sites in the same area of eastern Utah, this …
Bristlecone pine tree rings and volcanic eruptions over the last 5000 yr
Many years of low growth identified in a western USA regional chronology of upper forest border bristlecone pine ( Pinus longaeva and Pinus aristata ) over the last 5000 yr coincide with known large explosive volcanic eruptions and/or ice core signals of past eruptions. Over the last millennium the agreement between the tree-ring data and volcano/ice-core data is high: years of ring-width minima can be matched with known volcanic eruptions or ice…
A Test of “Annual Resolution” in Stalagmites Using Tree Rings
So-called annual banding has been identified in a number of speleothems in which the number of bands approximates the time interval between successive U-series dates. The apparent annual resolution of speleothem records, however, remains largely untested. Here we statistically compare variations in band thickness from a late Holocene stalagmite in Carlsbad Cavern, Southern New Mexico, USA, with three independent tree-ring chronologies form the sa…
Temperature Variability and the Northern Anasazi
A temperature reconstruction based on tree-rings from the San Francisco Peaks of northern Arizona is used to examine past temperature variability in relation to the thirteenth-century archaeological record in the northern Anas azi region. Three closely spaced cold periods that occurred in the 1200s can be tentatively linked to climatically effective explosive volcanism as recorded in the historical record and polar ice core record of eruptions. A…
