The anomaly has primarily been described as abrupt drying, but evidence of hydroclimate change at ca. 4 ka is inconsistent among sites globally, and few sites in North America document a major drought. Climate records from the southern Rocky Mountains demonstrate the challenge with diagnosing the extent and severity of the anomaly. Dune-field chronologies and a pollen record in southeast Wyoming reveal several centuries of low moisture at around 4.2 ka and prominent low stands in lakes in Colorado suggest the drought was unique amid Holocene variability, but detailed carbonate oxygen isotope (d18Ocarb) records from Colorado do not record it. We find new evidence from d18Ocarb in a small mountain lake in southeast Wyoming of an abrupt reduction in effective moisture or snowpack from approximately 4.2-4 ka that coincides in time with the other evidence from the southern Rocky Mountains and the western Great Plains of regional drying at around 4.2 ka. We find that the d18Ocarb in our record may reflect cool-season inputs into the lake, which do not appear to track the strong enrichment of heavy oxygen by evaporation during summer months today. The modern relationship differs from some widely applied conceptual models of lake-isotope systems and may indicate reduced winter precipitation rather than enhanced evaporation at ca. 4.2 ka. Inconsistencies among the North American records, particularly in d18Ocarb trends, thus show that site-specific factors can prevent identification of the patterns of multi-century drought. However, the prominence of the drought at ca. 4 ka among a growing number of sites in the North American interior suggests it was a regionally substantial climate event amid other Holocene variability.","pubRank":"1"}],"site":[{"NOAASiteId":"59173","siteName":"Highway 130 Lake","siteCode":null,"mappable":"Y","locationName":"Continent>North America>United States Of America>Wyoming","geo":{"geoType":"Feature","geometry":{"type":"POINT","coordinates":["41.3514","-106.2639"]},"properties":{"southernmostLatitude":"41.3514","northernmostLatitude":"41.3514","westernmostLongitude":"-106.2639","easternmostLongitude":"-106.2639","minElevationMeters":"3199","maxElevationMeters":"3199"}},"paleoData":[{"dataTableName":"Hwy130_2017_2AB","NOAADataTableId":"47677","earliestYear":11771,"mostRecentYear":-17,"timeUnit":"cal yr BP","earliestYearBP":11771,"mostRecentYearBP":-17,"earliestYearCE":-9821,"mostRecentYearCE":1967,"coreLengthMeters":null,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/paleolimnology/northamerica/usa/wyoming/highway130lake2021.txt","urlDescription":"NOAA Template File","linkText":"Highway 130 Lake Stable Isotope and Carbonate Data","variables":[{"cvDataType":"PALEOLIMNOLOGY","cvWhat":"depth variable>depth","cvMaterial":null,"cvError":null,"cvUnit":"length unit>centimeter","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"depth"},{"cvDataType":"PALEOLIMNOLOGY","cvWhat":"age variable>age","cvMaterial":null,"cvError":null,"cvUnit":"time unit>age unit>calendar year before present","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"age"},{"cvDataType":"PALEOLIMNOLOGY","cvWhat":"chemical composition>isotope>isotope ratio>delta 18O","cvMaterial":"geological material>identified mineral>carbonate>calcium carbonate","cvError":null,"cvUnit":"concentration unit>parts per notation unit>parts per thousand>per mil>per mil VPDB","cvSeasonality":null,"cvDetail":null,"cvMethod":"laboratory method>spectroscopy>mass spectrometry>isotope ratio mass spectrometry","cvAdditionalInfo":"lacustrine carbonates","cvFormat":"Numeric","cvShortName":"d18O"},{"cvDataType":"PALEOLIMNOLOGY","cvWhat":"chemical composition>isotope>isotope ratio>delta 13C","cvMaterial":"geological material>identified mineral>carbonate>calcium carbonate","cvError":null,"cvUnit":"concentration unit>parts per notation unit>parts per thousand>per mil>per mil VPDB","cvSeasonality":null,"cvDetail":null,"cvMethod":"laboratory method>spectroscopy>mass spectrometry>isotope ratio mass spectrometry","cvAdditionalInfo":"lacustrine carbonates","cvFormat":"Numeric","cvShortName":"d13C"},{"cvDataType":"PALEOLIMNOLOGY","cvWhat":"geological material>identified mineral>carbonate","cvMaterial":"geological material>bulk geological material>sediment","cvError":null,"cvUnit":"concentration unit>percent","cvSeasonality":null,"cvDetail":null,"cvMethod":"laboratory method>pyrolysis>loss on ignition","cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"percent_carb"},{"cvDataType":"PALEOLIMNOLOGY","cvWhat":"biological material>bulk biological material>organic matter","cvMaterial":"geological material>bulk geological material>sediment","cvError":null,"cvUnit":"concentration unit>percent","cvSeasonality":null,"cvDetail":null,"cvMethod":"laboratory method>pyrolysis>loss on ignition","cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"percent_org"},{"cvDataType":"PALEOLIMNOLOGY","cvWhat":"geological material>identified mineral>carbonate","cvMaterial":null,"cvError":null,"cvUnit":"rate unit>mass per area per time unit>gram per square centimeter per kiloyear","cvSeasonality":null,"cvDetail":null,"cvMethod":"laboratory method>pyrolysis>loss on ignition","cvAdditionalInfo":"core logger carbonate flux","cvFormat":"Numeric","cvShortName":"carb_flux"}],"NOAAKeywords":["earth science>paleoclimate>paleolimnology>physical properties","earth science>paleoclimate>paleolimnology>carbon isotopes","earth science>paleoclimate>paleolimnology>oxygen isotopes"]}]}]}],"reference":{"pastThesaurusSkos":"https://www.ncei.noaa.gov/access/paleo-search/skos/past-thesaurus.rdf","pastThesaurusExplorer":"https://www.ncei.noaa.gov/access/paleo-search/cvterms","gcmdKeywordThesaurus":"https://earthdata.nasa.gov/earth-observation-data/find-data/idn/gcmd-keywords"},"dataLicenseDescription":null,"dataLicenseUrl":null}
