SAMPLE INFO : Ahklun Mountains-3.1ka-Tephra-Pop.1_average
Sample ID:Ahklun Mountains-3.1ka-Tephra-Pop.1_average
Station ID:Ahklun_Mountains_Regional_Tephra
Latitude:59.6
Longitude:-160.39998
Datum:NAD83
Sample Type 1:Tephra Fall
 Text Description:
Average composition of samples from Lone Spruce Pond (UA1964) and Waskey Lake (Levy et al. 2004) (UA1793). The bed comprises pure glass shards in both lakes, and an undated but possibly correlative bed is also found in Cascade Lake (neither analyzed nor dated).
