Hi baynzer, I found a definition of "coastal bluff" for you: What is a coastal bluff? http://www.maine.gov/doc/nrimc/mgs/pubs/series/descrip-bluff.htm ...a coastal bluff is defined as a steep shoreline slope formed in sediment (loose material such as clay, sand, and gravel) that has three feet or more of vertical elevation just above the high tide line. Cliffs or slopes in bedrock (ledge) surfaces are not bluffs and are not subject to significant erosion in a century or more. Beaches and dunes do not form bluffs, except along the seaward dune edge as a result of erosion. The map sidebar [at the link below] contains additional information describing coastal bluffs..." Explanation from Coastal Bluffs Map http://mainegov-images.informe.org/doc/nrimc/mgs/pubs/series/bluffs/bluff-exp.pdf There's a couple images here, they did take a while to load, be patient. Hope this helps! ~~Cynthia Search terms: "coastal bluff"
