Holocene lake-level changes in Celestine Lake, Canadian Rocky Mountains, identified using stable isotopes, geochemistry, and mineralogy
A multiproxy lake-level reconstruction from Celestine Lake, located in Jasper National Park, Alberta, Canada, provides quantifiable evidence for Holocene precipitation-evaporation balance. Celestine Lake produces authigenic carbonate in its shallow waters while preserving organic sediments in the deeper basin. Sedimentary analysis of three cores collected from Celestine Lake along a shallow- to deep-water transect, analysis of modern lake water g…

Taming Fogo Island
Cabo Verde remained uninhabited until 1460 CE, when European sailors founded a settlement in Santiago, and soon after in Fogo island. The degree to which different island ecosystems in Cabo Verde have been transformed by humans remains uncertain because of a scarcity of historical information and archaeological evidence. Disentangling these processes from natural ones is complicated in islands with a history of volcanic impacts and other natural …
Dropstones in Lacustrine Sediments as a Record of Snow Avalanches—A Validation of the Proxy by Combining Satellite Imagery and Varve Chronology at Kenai Lake (South-Central Alaska)
Snow avalanches cause many fatalities every year and damage local economies worldwide. The present-day climate change affects the snowpack and, thus, the properties and frequency of snow avalanches. Reconstructing snow avalanche records can help us understand past variations in avalanche frequency and their relationship to climate change. Previous avalanche records have primarily been reconstructed using dendrochronology. Here, we investigate the…
A re-examination of the three most prominent Holocene tephra deposits in western Canada
Origin of last-glacial loess in the western Yukon-Tanana Upland, central Alaska, USA
Loess is widespread over Alaska, and its accumulation has traditionally been associated with glacial periods. Surprisingly, loess deposits securely dated to the last glacial period are rare in Alaska, and paleowind reconstructions for this time period are limited to inferences from dune orientations. We report a rare occurrence of loess deposits dating to the last glacial period, ~19 ka to ~12 ka, in the Yukon-Tanana Upland. Loess in this area is…
Middle Pleistocene (MIS 7) to Holocene fossil insect assemblages from the Old Crow basin, northern Yukon, Canada
The variegated (VT) tephra
Rapid changes in the level of Kluane Lake in Yukon Territory over the last millennium
The level of Kluane Lake, the largest lake in Yukon Territory, was lower than at present during most of the Holocene. The lake rose rapidly in the late seventeenth century to a level 12 m above present, drowning forest and stranding driftwood on a conspicuous high-stand beach, remnants of which are preserved at the south end of the lake. Kluane Lake fell back to near its present level by the end of the eighteenth century and has fluctuated within…
