Late Pleistocene Littoral Deposits In The Deming Sand At Bellingham Bay, Washington, And Their Implications For Relative Sea Level Changes, Stacy J. (Stacy Joanna) Weber

WWU Graduate School Collection

Recent mass wasting of sea cliffs along Bellingham Bay in Northwest Washington has exposed late Pleistocene littoral deposits in the Deming sand, which is underlain by Kulshan glaciomarine drift (gmd) and overlain by Bellingham glaciomarine drift (Easterbrook 1963). Marine shells in the Kulshan gmd were dated at 12,210 ± 80 ¹⁴C-yrs B. P. and marine shells in the Deming sand were dated at 11,760 ± 85 and 11,685 ± 85 ¹⁴C-yrs B. P. Marine shells in the Bellingham gmd were dated at 12,150 + 210 ¹⁴C-yrs B. P.
