| Text Description: | Tephra layer C comprises two units including upper (C2) and lower (C1) fall deposits that possibly represent two phases of the same eruption. The C2 tephra unit is 12-15 cm thick and shows distinct reverse grading with the largest pumice fragments at the top. Mingling of some prehistoric magmas occurred, because one C2 clast consists of white pumice containing bands of much darker volcanic rock. Light gray pumice; near South Point |
