Every year since 1982, Joseph Kelley captured photos of the fastest deteriorating portion of Maine’s coast, located in Camp Ellis, for use in his work as a state marine geologist, and research and teaching at the University of Maine.

Later this fall, the public will have the opportunity to view decades of geologic transformation captured in the images taken of the Saco-area shoreline as well as thousands of others depicting dramatic changes in Maine’s coastal vistas.
