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. Unit C1 is a light gray, coarse-grained, andesitic, normally graded tephra deposit that is 60-70 cm thick and overlies soil. Light gray pumice; near South Point
