Sample type 1: Tephra Fall
Color: white to gray
Final unit:
Text Description: Subhorizontal, microfaulted bed with a maximum thickness of 3 cm. Locally, it is layered with a white base, gray middle unit, and a grayish-white cap interbedded with orange-brown (2.5Y6/3) soliflucted silt with numerous oxidation bands and nodules. Deformed into pods, but, in most places, these layers are very thin and repeat vertically to give a banded appearance. Sharp lower contact and diffuse upper contact. Unclear if upper grayish-white cap is primary or reworked.
