Lecture date: February 18, 2015. Gary Griggs discussed how over the past century, humans have changed the California coast in significant ways.

In a state identified with change, California’s 1,100-mile coastline lives up to the reputation. Storm waves attack sea cliffs, earthquakes trigger landslides, and ocean waves relentlessly move sand along the shoreline, bringing it and taking it away. Griggs will discuss how over the past century, humans have changed the coast in significant ways, particularly in Southern California, where extensive stretches of coast have been completely altered. Yet there are areas along the north and central coast where you may not see another person for an entire day, and the shoreline looks like it did a hundred years ago.

Griggs, professor of Earth and planetary sciences at University of California, Santa Cruz, is the author of California Coast from the Air, a collection of aerial photographs with captions by Griggs and architect Deepika Shrestha Ross.
