Map showing Features and Displacements of the Scenic Drive Landslide, La Honda, California, During the Period March 31, 2005 - November 5, 2006

The Scenic Drive landslide in La Honda, San Mateo County, California began movement during the El Niño winter of 1997-98. Recurrent motion occurred during the mild El Nino winter of 2004-2005 and again during the winter of 2005-06. This report documents the changing geometry and motion of the Scenic Drive landslide in 2005-2006, and it documents changes and persistent features that we interpret to reflect underlying structural control of the landslide. We have also compared the displacement history to near-real time rainfall history at a continuously recording gauge for the period October 2004-November 2006. [Summary provided by the USGS.]
