Gravel Barrier Morphology: Olympic National Park, Washington State, U.S.A.

Patrick J. McKay, Thomas A. Terich


Three gravel barriers studied along the Olympic Coast of Washington State display morphology and textural characteristics similar to those barriers reported along the coasts of Ireland, England and Nova Scotia. Resistant headlands serve as anchor points for two of the three barriers. Headlands are not, however a necessary prerequisite for their development. These barriers seem to follow an evolutionary model of development and destruction somewhat similar to those in the literature.
