Short summary
A 180 m long (ca. 274 year) ice core was drilled in the saddle of the Aurora Peak in Alaska (63.52° N, 146.54° W; elevation: 2,825 m). The ice core samples were derived with O-bis-(trimethylsilyl)trifluoroacetamide with 1 % trimethylsilyl chloride and pyridine followed by gas-chromatography–mass-spectrometry analyses. Levoglucosan, dehydroabietic acid and vanillic acid are reported for the first time from the alpine glacier to better understand historical biomass burning.
