Core collection was at Moss Lake, which is located within the Tolt River basin in King County in the Cascade foothills, approximately 530 km north east of Crater Lake (Mount Mazama). Moss Lake has a diameter of approximately 200 m with a maximum depth of 4.5 m. Data has been obtained from lake sediment cores from Moss Lake, Washington. Two cores were taken, one from the centre (MLC) and one from the fringe (MLF).
This data set provides results from various stratigraphic analyses in the central core, loss on ignition given as a percentage, and the magnetic susceptibility, this was done using a loop core scanner.Radiocarbon dates are provided in Egan et al. (2016).
