The majority of the Maine coast--about 58%--is characterized is hard rock; some areas may have rocky cliffs that might also be called bluffs. The rocky coast is relatively stable over time, but soil can erode along the shoreline. Another 40% or 1,400 miles of Maine's shoreline has soft bluffs: tall (over three feet), with steep slopes of loose rock, gravel, clay, or sand that easily erode. One of the biggest hazards associated with soft bluffs is the threat of landslides, especially in high coastal bluffs made of muddy sediment.
