However, because moraine chronologies are characteristically discontinuous, Holocene glacier fluctuations and their climatic drivers remain ambiguous, and future glacier changes are uncertain. Here, we construct a continuous 10-thousand-year (ka) record of glacier activity in the Teton Range, Wyoming, using glacial and environmental indicators in alpine lake sediments. We show that Teton glaciers persisted in some form through early Holocene warmth, likely as small debris-covered glaciers or rock glaciers. Subsequent Neoglacial ice expansion began ~6.3 ka, with two prominent glacier maxima at ~2.8 and 0.1 ka that were separated by a multicentennial phase of ice retreat. Comparison with regional paleoclimate records suggests that glacier activity was dominantly controlled by winter precipitation variability superposed on long- term Holocene temperature trends, offering key insights into western U.S. glacier resilience and vulnerability to future warming. #--------------------------------------- # Funding_Agency # Funding_Agency_Name: US National Science Foundation # Grant: 1755067 #--------------------------------------- # Site_Information # Site_Name: Delta Lake, Grand Teton National Park # Location: Wyoming # Northernmost_Latitude: 43.7319 # Southernmost_Latitude: 43.7319 # Easternmost_Longitude: -110.7720 # Westernmost_Longitude: -110.7720 # Elevation_m: 2755 #--------------------------------------- # Data_Collection # Collection_Name: SURP16 OM flux, BSI flux Larsen2020 # First_Year: 10076 # Last_Year: -11.5 # Time_Unit: calendar year before present # Core_Length_m: 10.6 # Parameter_Keywords: physical properties # Notes: #--------------------------------------- # Chronology_Information # Chronology: # See Supplemental Material published with manuscript for all chronological information #--------------------------------------- # Variables # PaST_Thesaurus_Download_Resource: https://www.ncei.noaa.gov/access/paleo-search/skos/past-thesaurus.rdf # PaST_Thesaurus_Download_Description: Paleoenvironmental Standard Terms (PaST) Thesaurus terms, definitions, and relationships in SKOS format. # # Data variables follow that are preceded by "##" in columns one and two. # Variables list, one per line, shortname-tab-var components: what, material, error, units, seasonality, data type, detail, method, C or N for Character or Numeric data) # ## SURP16_Age_yrBP age,,,calendar year before present,,Paleolimnology,,,N, ## OM_Flux accumulation rate,organic matter,,milligram per square centimeter per year,,Paleolimnology,,loss on ignition,N, ## Bsi_Flux accumulation rate,sediment,,,,Paleolimnology,,fourier transform infrared spectroscopy,N,biogenic silica #------------------------ # Data: # Data lines follow (have no #) # Data line format -
