Abstract
The evidence presented suggests that terraces and related features found on Bay View Ridge, Skagit County, Washington are raised marine in origin, and formed 13,000 - 11,000 years before present during the Everson Interstade of the Fraser Glaciation. Methods of investigation included topographic profiling, geologic mapping of surface deposits, identifying primary sedimentary structures, grain-size distribution analyses, identifying textural surface features on quartz grains utilizing the Scanning Electron Microscope and radiocarbon age dating.
Little or no measurable differential vertical tectonic and/or glacio-isostatic relative movement has occurred at Bay View Ridge since the Everson Interstade. Volcanic ash found in two peat bogs on Bay View Ridge is believed to have resulted from the eruptions of Mount Mazama.
