Tree-ring crossdates for a First Millennium AD advance of Tebenkof Glacier, southern Alaska
Tree-ring crossdates from glacially killed logs show that Tebenkof Glacier advanced into a forefield forest in the AD 710s and 720s. Recession from this First Millennium AD (FMA) advance occurred before the 950s, after which the ice margin readvanced in the 1280s to 1320s at the start of the Little Ice Age (LIA). A more extensive LIA advance was underway from the 1640s to 1670s, and the terminus stayed at or near its LIA maximum until the 1890s. …
A 1119-year tree-ring-width chronology from western Prince William Sound, southern Alaska
Living and subfossil trees from glacier forefields are used to develop a 1119-year-long tree-ringwidth chronology. Strong cross-dating among ring-width series from sites up to 60 km apart and an analysis of sample homogeneity support combination of all samples into a single, regional composite chronology. Comparison with instrumental climate data indicates May through July temperatures of the growth year are the primary control on ring-widths. Mu…
Tree-ring-dated‘Little Ice Age’ histories of maritime glaciers from western Prince William Sound, Alaska
Tree-ring studies at 13 glacier forefields in western Prince William Sound show‘Little Ice Age’ glacial fluctuations were strongly synchronous on decadal timescales. Cross-dated glacially overrun trees at eight sites indicate ice margins advanced in the early (late twelfth through thirteenth centuries) and middle (seventeenth to early eighteenth centuries)‘Little Ice Age’. Tree-ring dates of 22 moraines at 13 glaciers show two main periods of sta…
Late-Holocene glaciation and twentieth- century retreat, northeastern Brooks Range, Alaska
Lichenometric dating of moraines deposited by eight glaciers in the northeastern Brooks Range suggests major glacial advances or stillstands at about 2600, 1000, 450, and 60 lichenometric (L) years BP. The latter two advances of the early-middle and latest part of the 'Little Ice Age', respectively, formed promi nent moraines at all glaciers studied. In response to overall twentieth-century warming, these glaciers have retreated at average rates …
Neoglacial fluctuations and sedimentation of an iceberg-calving glacier resolved with tree rings (kenai Fjords national park, Alaska)
Paleoecological Interpretation and Age of an Interstadial Lake Bed in Western New York
Pollen assemblages from a 6.6-m exposure of Pleistocene lake silt in central western New York consist of anomalous mixtures dominated by spruce, pine, and sedge but with a significant representation of deciduous forest elements. Leaves of Dryas integrifolia and plants of the terrestrial moss Distichium from the lake silt yielded AMS ages of 24,900 ± 1000 and 24,180 ± 900 yr B.P., indicating that the silt was deposited during the middle Wisconsina…
Holocene Glaciation of the Arrigetch Peaks, Brooks Range, Alaska
Eleven cirque glaciers and associated deposits within the granitic Arrigetch Peaks of the west-central Brooks Range face north, minimizing insolation. Shading by surrounding mountainous terrain decreases insolation on these landforms even more significantly, favoring the formation of glacier-cored moraines. Comparison of glacier photographs taken in 1911, 1962, and 1979 reveals a record of decelerating recession. Geomorphic and lichenometric mapp…
The glacial history of the ice-free area, southern Victoria Land, Antarctica
The Victoria Valley system, Wright Valley and Taylor Valley, often referred to colloquially as the dry-valley area, together cover about 4 000 km 2 in the Transantarctic Mountains west of McMurdo Sound (Fig 1) and constitute the core of the largest ice-free area in Antarctica. It is a cold desert area, with high winds, low temperatures, low precipitation, and a strong positive radiation balance (Bull, 1966)
