  • Ice-Flow Dynamics During the Final Stage of the Fraser Glaciation (MIS2) in the Fraser Lowland, BC, Canada

    Open AccessRaphael Gromig, Kenya Franz et al.ARTICLEQuaternary2025

    Although the Late Pleistocene glaciation history of the Fraser Lowland (BC, Canada) is relatively well studied, little is known about ice-flow directions during the last glaciation (Fraser glaciation). Lidar imagery from the western Fraser Lowland was used to identify and interpret previously unrecognized glacial landforms in a heavily urbanized and vegetated area. This indicates patterns of ice flow during the latest stage of the Fraser glaciati…

  • New insights into the glacial and relative sea-level history of the western Fraser Lowland based on sediment cores from geotechnical drilling for the Evergreen Tunnel, British Columbia, Canada

    Open AccessL E Jackson, Brent Ward et al.ARTICLEQuaternary Research2024

    Geotechnical drilling for a tunnel between Port Moody and Burnaby, BC, Canada, uncovered a buried fjord. Its sedimentary fill has a thickness of at least 130 m and extends more than 37 m below present mean sea level. Recovered sediments record cyclical growth and decay of successive Cordilleran ice sheets. The oldest sediments comprise 58 m of almost stoneless silt conformably overlying ice-proximal sediments and till, which in turn overlie bedro…

  • Glacier fluctuation chronology since the latest Pleistocene at Mount Rainier, Washington, USA

    Open AccessMary Samolczyk, Mary A Samolczyk et al.ARTICLEQuaternary Research2024

    Large stratovolcanoes in the Cascade Range have high equilibrium-line altitudes that support glaciers whose Holocene and latest Pleistocene advances are amenable to dating. Glacier advances produced datable stratigraphic sequences in lateral moraines, which complement dating of end moraines. New mapping of glacial deposits on Mount Rainier using LIDAR and field observations supports a single latest Pleistocene or early Holocene advance. Rainier R…

  • Impacts of Loss of Cryosphere in the High Mountains of Northwest North America

    Open AccessJohn J Clague, Dan H ShugarARTICLEQuaternary2023

    Global atmospheric warming is causing physical and biotic changes in Earth’s high mountains at a rate that is likely unprecedented in the Holocene. We summarize changes in the presently glacierized mountains of northwest North America, including a rapid and large reduction in glacier ice and permafrost, a related increase in slope instability and landslides, river re-routing and other hydrological changes, and changing aquatic ecosystems. Atmosph…

  • Reconstruction of climate and ecology of Skagit Valley, Washington, from 27.7 to 19.8 ka based on plant and beetle macrofossils

    Open AccessJon L Riedel, Alice Telka et al.ARTICLEQuaternary Research2022

    Glacial lake sediments exposed at two sites in Skagit Valley, Washington, encase abundant macrofossils dating from 27.7 to 19.8 cal ka BP. At the last glacial maximum (LGM) most of the valley floor was part of a regionally extensive arid boreal (subalpine) forest that periodically included montane and temperate trees and open boreal species such as dwarf birch, northern spikemoss, and heath. We used the modern distribution and climate of 14 speci…

  • Poverty control policy may affect the transition of geological disaster risk in China

    Open AccessHengxing Lan, Naiman Tian et al.ARTICLEHumanities and Social Sciences…2022

    The Chinese government has implemented measures to reduce poverty in the country. Specifically, the Targeted Poverty Alleviation (2013–2020) policy is a set of unique, large-scale and precise poverty control measures undertaken by China in an effort to eliminate absolute poverty. Deeply impoverished areas in the mountainous regions of Southwest China are also particularly prone to geological disasters. A poverty control policy might reduce risk f…

  • Evaluating urban flood risk using hybrid method of Topsis and machine learning

    Open AccessElham Rafiei-Sardooi, Ali Azareh et al.ARTICLEInternational Journal of Disaster…2021

    With the growth of cities, urban flooding has increasingly become an issue for regional and national governments. The destructive effects of floods are magnified in cities. Accurate models of urban flood susceptibility are required to mitigate this hazard mitigation and build resilience in cities. In this paper, we evaluate flood riskin Jiroft city, Iran, using a combination of machine learning and decision-making methods. Flood hazard maps were …

  • Late Holocene fluctuations of Stoppani Glacier, southernmost Patagonia

    Open AccessBrian Menounos, Lyssa Maurer et al.ARTICLEQuaternary Research2020

    Some lateral moraines contain a rich record of Holocene glacial expansion. Previous workers have used such evidence to document glacial fluctuations in western Canada, Alaska, and the U.S. Pacific Northwest, but similar studies in Patagonia are uncommon. Here we report on the late Holocene behavior of Stoppani Glacier, a 75 km 2 glacier sourced in the Cordillera Darwin, southernmost Patagonia. Based on radiocarbon-dated wood and organic material …

  • Shallow Landslide Susceptibility Mapping

    Open AccessViet‐Ha Nhu, Ataollah Shirzadi et al.ARTICLEInternational Journal of…2020

    Shallow landslides damage buildings and other infrastructure, disrupt agriculture practices, and can cause social upheaval and loss of life. As a result, many scientists study the phenomenon, and some of them have focused on producing landslide susceptibility maps that can be used by land-use managers to reduce injury and damage. This paper contributes to this effort by comparing the power and effectiveness of five machine learning, benchmark alg…

  • Landslide Susceptibility Mapping Using Machine Learning Algorithms and Remote Sensing Data in a Tropical Environment

    Open AccessViet‐Ha Nhu, Ayub Mohammadi et al.ARTICLEInternational Journal of…2020

    We used AdaBoost (AB), alternating decision tree (ADTree), and their combination as an ensemble model (AB-ADTree) to spatially predict landslides in the Cameron Highlands, Malaysia. The models were trained with a database of 152 landslides compiled using Synthetic Aperture Radar Interferometry, Google Earth images, and field surveys, and 17 conditioning factors (slope, aspect, elevation, distance to road, distance to river, proximity to fault, ro…

    Open AccessDan H Shugar, K A Colorado et al.ARTICLEJournal of Maps2019

    This paper describes a collaboration between a visual artist and geoscientists, who together viewed the same rugged, high mountain landscape through different, yet complementary, lenses. We pair scientific mapping and historic comparative photography with a series of site-specific sculptural installations to interpret the dramatic geological changes that occurred at Kaskawulsh Glacier, Yukon, in the spring of 2016. In the summer of that year, art…

  • Paleoecology and ice limits of the early Fraser glaciation (Marine Isotope Stage 2) on Haida Gwaii, British Columbia, Canada

    Open AccessRolf W Mathewes, John J ClagueARTICLEQuaternary Research2017

    Our study combines new geological and paleoecological information to reconstruct the glacial history and terrestrial paleoenvironments on Haida Gwaii during the advance phase of the Fraser glaciation (Marine Isotope Stage 2). At Cape Ball on eastern Graham Island, five accelerator mass spectrometry radiocarbon ages ranging from 23,200±280 to 26,650±390 14 C yr BP (ca. 27,000–31,400 cal yr BP) record the earliest approach of mainland glaciers to H…

  • Provenance and Deposition of Glacial Lake Missoula Lacustrine and Flood Sediments Determined from Rock Magnetic Properties

    Open AccessMichelle Andrée Hanson, Randolph Jonathan Enkin et al.ARTICLEQuaternary Research2015

    Repeated outburst flooding from glacial Lake Missoula, Montana, affected large areas of Washington during Marine Oxygen Isotope Stage 2 (29–14 ka). We present the first high-resolution rock magnetic results from two sites that are critical to interpreting these outburst floods and that provide evidence of sediment provenance: glacial Lake Missoula, the source of the floods; and glacial Lake Columbia, where floodwaters interrupted sedimentation. M…

  • Alpine glaciers and permanent ice and snow patches in western Canada approach their smallest sizes since the mid-Holocene, consistent with global trends

    Open AccessJohannes Koch, John J Clague et al.ARTICLEThe Holocene2014References: 23

    Most alpine glaciers in the Northern Hemisphere reached their maximum extents of the Holocene between ad 1600 and 1850. Since the late 1800s, however, glaciers have thinned and retreated, mainly because of atmospheric warming. Glacier retreat in western Canada and other regions is exposing subfossil tree stumps, soils and plant detritus that, until recently, were beneath tens to hundreds of metres of ice. In addition, human artefacts and caribou …

  • Tree-ring dating of the nineteenth-century advance of Brady Glacier and the evolution of two ice-marginal lakes, Alaska

    Open AccessDenny M Capps, Gregory C Wiles et al.ARTICLEThe Holocene2011References: 2

    We utilized dendrochronology and precise elevation-constrained mapping to date glacially overridden and drowned trees at the margin of Brady Glacier in southeast Alaska. This technique allowed determination of the timing of the former tidewater glacier’s last advance and consequent formation and filling of two marginal lakes. The subfossil tree-ring chronology spans the interval from AD 1370 to 1861. Brady Glacier impounded Spur Lake to an elevat…

  • Timing and extent of early marine oxygen isotope stage 2 alpine glaciation in Skagit Valley, Washington

    Open AccessJon L Riedel, John J Clague et al.ARTICLEQuaternary Research2010

    Twenty-two new radiocarbon ages from Skagit valley provide a detailed chronology of alpine glaciation during the Evans Creek stade of the Fraser Glaciation (early marine oxygen isotope stage (MIS) 2) in the Cascade Range, Washington State. Sediments at sites near Concrete, Washington, record two advances of the Baker valley glacier between ca. 30.3 and 19.5 cal ka BP, with an intervening period of glacier recession about 24.9 cal ka BP. The Baker…

  • Expansion of outlet glaciers of the Juneau Icefield in northwest British Columbia during the past two millennia

    Open AccessJohn J Clague, Johannes Koch et al.ARTICLEThe Holocene2010References: 12

    Radiocarbon and dendrochronological dating of glacially overridden stumps and detrital wood indicates that two outlet glaciers of the Juneau Icefield advanced shortly before the ‘Little Ice Age’. Tulsequah Glacier advanced to within 2.4 km of its all-time Holocene limit between AD 865 and AD 940. Llewellyn Glacier, one of the largest glaciers in British Columbia, advanced sometime between AD 300 and AD 500, and reached to within 400 m of its Holo…

  • Tree-Ring Dates for the Maximum Little Ice Age Advance of Kaskawulsh Glacier, St. Elias Mountains, Canada

    Open AccessAlberto V Reyes, Brian H Luckman et al.ARTICLEARCTIC2009

    A dendroglaciological study at Kaskawulsh Glacier provides the first calendar dating of a Little Ice Age glacier advance in the northeast St. Elias Mountains of Yukon Territory. Ring series from white spruce trees, Picea glauca (Moench) Voss, that had been sheared, tilted, and killed by deposition of till at the glacier’s terminal moraine were cross-dated with a millennium-length ring-width chronology developed at a site near the south end of Klu…

  • Plant Macrofossils Associated with an Early Holocene Beaver Dam in Interior Alaska

    Open AccessSimon Robinson, Simon G Robinson et al.ARTICLEARCTIC2009

    Dynamic climate changes and expansion of new biomes characterize the late Pleistocene–early Holocene of eastern Beringia. Analysis of plant macrofossils from an early Holocene (ca. 9300 14C yrs BP) beaver dam in central Alaska provides insight into the local environment and vegetation. The plant macrofossil assemblage comprises remains of trees and shrubs, graminoids, and forbs, including Betula sp., Carex sp., Rubus sp., Eleocharis sp., Scirpus …

  • Exploring Stó

    Open AccessD Lepofsky, David M Schaepe et al.ARTICLEAmerican Antiquity2009Cited by: 25References: 44

    Social scientists recognize a complex and iterative relationship between the built environment and social identities. Here, we explore the extent to which household and settlement remains may be used as archaeological correlates of collective identities among the Stó:lō-Coast Salish peoples of the Fraser River Valley. Using data from six recently tested archaeological sites we begin with the household and explore expressions of identity at variou…

  • Timing and cause of water level fluctuations in Kluane Lake, Yukon Territory, over the past 5000 years

    Open AccessJanice Brahney, John J Clague et al.ARTICLEQuaternary Research2008

    We reconstructed late Holocene fluctuations of Kluane Lake in Yukon Territory from variations in bulk physical properties and carbon and nitrogen elemental and isotopic abundances in nine sediment cores. Fluctuations of Kluane Lake in the past were controlled by changes in climate and glaciers, which affected inflow of Slims and Duke rivers, the two largest sources of water flowing into the lake. Kluane Lake fluctuated within a narrow range, at l…

  • Advance of alpine glaciers during final retreat of the Cordilleran ice sheet in the Finlay River area, northern British Columbia, Canada

    Open AccessThomas R Lakeman, John J Clague et al.ARTICLEQuaternary Research2008

    Sharp-crested moraines, up to 120 m high and 9 km beyond Little Ice Age glacier limits, record a late Pleistocene advance of alpine glaciers in the Finlay River area in northern British Columbia. The moraines are regional in extent and record climatic deterioration near the end of the last glaciation. Several lateral moraines are crosscut by meltwater channels that record downwasting of trunk valley ice of the northern Cordilleran ice sheet. Othe…

  • Pre-`Little Ice Age' glacier fluctuations in Garibaldi Provincial Park, Coast Mountains, British Columbia, Canada

    Open AccessJohannes Koch, Gerald Osborn et al.ARTICLEThe Holocene2007Cited by: 5References: 7

    Holocene glacier fluctuations prior to the `Little Ice Age' in Garibaldi Provincial Park in the British Columbia Coast Mountains were reconstructed from geomorphic mapping and radiocarbon ages on 37 samples of growth-position and detrital wood from glacier forefields. Glaciers in Garibaldi Park were smaller than at present in the early Holocene, although some evidence exists for minor, short-lived advances at this time. The first well-documented …

  • Rapid changes in the level of Kluane Lake in Yukon Territory over the last millennium

    Open AccessJohn J Clague, Brian H Luckman et al.ARTICLEQuaternary Research2006

    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…
