multiple, discontinuous or continuous for several hundred feet. Structural 
composition usually indicates the presence of beach material sediments 
such as pebbles, gravel and sand or sandy silt. The upper portion 
of the ridge in many instances is composed of unconsolidated sandy, 
fine sediment, whereas the lower portion often carries gravelly, stony 
or sandy mixtures. Vegetative cover was visually estimated, plant 
species identified and substrate characteristics noted.
