Text Description: Average composition of samples from Lone Spruce Pond (UA1785), Arolik Lake (Kaufman et al. 2003) (UA1791), and Sunday Lake (UA1789). Tephra C is composed entirely of crystal-rich blocky glass and pumice. It contains both brown and clear glass. Its age overlaps with that of a prominent tephra in Nimgun Lake in the Ahklun Mountains, which was not analyzed.
