Bunces Key, a narrow, linear, barrier island on the west-central coast of Florida, was founded in 1961. Its growth and development since that time is well documented by aerial photography. Cores taken from the Key and surrounding areas reveal a stratigraphic succession of facies reflecting rapid vertical aggradation. Sedimentation began on a gently sloping platform through the landward migration of large scale bedforms (sand waves) during fair weather periods. Migration of these bedforms ceased when emergence and lack of continued overwash precluded further movement. Vertical accretion to supratidal levels resulted from the continued onshore transport of sediment and subsequent welding ...
