Presentation Title: A Multi-proxy reconstruction of post-glacial environmental change from a core of Soldier Lake, Nevada

Section: Poster Session Group 2 2

Location: , Great Hall

Date & Time: Friday, April 19, 2013 - 2:45pm - 3:30pm


We analyzed a core retrieved from Soldier Lake, a tarn at 2775 m asl in the Ruby Mountains of northeastern Nevada, to reconstruct a record of post-glacial Holocene environmental change. The core penetrated to a depth of 415 cm below the sediment-water interface. Three AMS radiocarbon analyses indicates that the core extends to at least 26065 cal ka BP. A layer of tephra encountered at a depth of 190 cm was correlated with the Mt. Mazama eruption by geochemical fingerprinting. Multi-proxy laboratory analysis of the core included measurements of magnetic susceptibility (MS), water content, loss on ignition (LOI), estimated bulk density (BD), grain size distribution (GS), and carbon to nitrogen ratio (C/N). Analysis of results will support development of an environmental history that will be compared with other post-glacial lacustrine records from the region, in particular Angel and Overland Lakes in the Ruby Mountains, NV.
