 Text Description:
Moderately sorted scoria unit that pinches and swells but is on average 3-5 cm thick. Some scoria are flattened and ribbon-like being up to 2.5 cm in length although the average clast size is closer to 5 mm. Free plagioclase crystals are present, some, which are chalk-white in color, and approximately 1 mm in size.

18JFLPV03755.54496-161.85553Larsen, J. F.2018-07-17 PavlofSection on west side of Caribou Creek, approximately 14.5 km N/NE of Pavlof. Steeply sloping buff comprised of at least 10 m of diamicton capped by a sequence of soil with tephra. Lower portion of diamicton cap is primarily soil with some tephra, whereas upper portion contains more tephra than below. Soil is very loose and uncompacted (very easy to shovel) and not very organic-rich. Section is east of Trader Mountain. Jessica Larsen described and Katie Mulliken scribed. Moderately sorted scoria unit that pinches and swells but is on average 3-5 cm thick. Some scoria are flattened and ribbon-like being up to 2.5 cm in length although the average clast size is closer to 5 mm. Free plagioclase crystals are present, some, which are chalk-white in color, and approximately 1 mm in size.18JFLPV037ITephra FallCumulateWhole-rock 52.90479862 1.178051801 19.44121729 9.241144665 0.181966504 3.824102031 9.06233181 3.315280272 0.586379622 0.26471744 99.51331515231XRF9.241144665LOI=0 0.487893669 9.933144799 220.4268166 408.4819662 7.906181284 20.0840881 3.014919902 14.22462641 3.915314607 1.354869322 4.403940262 0.778262605 4.808046813 1.021449437 2.758563129 0.417613317 2.537678977 0.40518165 25.22008816 99.12191139 3.162967793 2.611760574 0.247799214 3.663934666 0.858585404 0.426244641 27.84824986 243.738 11.385 4.554 38.61 90.684 21.483 15231ICPMS: Cs, Rb, Ba, Sr, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Y, Zr, Nb, Hf, Ta, Pb, Th, U, Sc; XRF: V, Cr, Ni, Cu, Zn, Ga;
