Some homes above Gleason’s Beach on the Sonoma Coast have been lost in years past, while others remain at risk.

  Gary Griggs, a professor of  Earth and Planetary Sciences at UC Santa Cruz , has been tracking the eroding cliffs at Gleason Beach for the past decade and a half. He says his periodic return visits show that the problems there continue to advance slowly but persistently.

Last year, CalTrans began developing  plans to move Highway One further inland as it passes the Gleason Beach area. While this is one of the most acute threats to the highway, Griggs notes that the highway agency have a lot to be concerned about up and down the California coast.
