SAMPLE INFO : CU1153
Sample ID:CU1153
Station ID:Cabin_Lake
Latitude:60.5
Longitude:-145.39998
Datum:NAD83
Sample Type 1:Tephra Fall
 Text Description:
Sample 11-CB-4-2 131, IGSN: BOF000007. Yielded the smallest amount of material for microanalysis, but the highest concentration of glass. The glass is a homogeneous high-silica rhyolite, with a type I affinity. Most fragments are smaller than 40 mm. Blocky and bubble-wall morphologies are common. Pumice and a few tricuspate shards are also present.

Cabin_Lake60.5-145.39998Unknown, Unknown 2571 ± 143 14C; 8851; Age is approximate. Age model derived from eight radiocarbon ages obtained from core 10-CB-1C and ten from 11-CB-4. Radiocarbon ages were calibrated to calendar years before AD 1950 (cal a BP) using calib v6.0 with the INTCAL09 calibration curve (Stuiver and Reimer, 1993). The program clam.r v2 was used to create a smoothed spline (smooth=0.4) fit for the ageCabin Lake is a small, shallow lake (0.1 km square; 4.8 m in depth) located at the base of the Chugach Mountains at an elevation of 40 m asl. The lake is about 16 km east of Cordova, Alaska, in the eastern Prince William Sound, and 5 km west of the terminus of Sheridan Glacier. It is located on the northern edge of the present-day outwash plain of Sheridan Glacier and does not currently receive meltwater from the glacier. Location imprecisely georeferenced from Figure 1 of Zander and others (2013). Sample 11-CB-4-2 131, IGSN: BOF000007.
