SDAG One Stop Wonder - Calle Guadalajara Landslide - San Clemente

Calle Guadalajara Landslide - One Stop Wonder

Calle Guadalajara Landslide - One Stop Wonder

Stephen Jacobs is leading our first OSW of 2019 to observe a large landslide in San Clemente. The OSW is scheduled for Saturday, January 5, 2019 from 10am to 12 noon.

Access to the landslide complex is via a trail leading from Calle Guadalajara. Parking near the trailhead is along the street on Calle Guadalajara between Calle Corral and Calle Reata in San Clemente. The proposed meeting time will be 10:00 am to 12:00 pm on Saturday, January 5, 2019.

An interesting landslide complex in an open area of San Clemente has progressed in size since about the mid 1990s. It represents a series of reactivated slides within an ancient landslide complex underlain by the Capistrano Formation according to the Geologic Map of the Dana Point Quadrangle mapped by Tan (1999). The latest and most prominent reactivated portion of the slide complex, which apparently formed in about 2011, is near the eastern part of the mapped area of the ancient landslide complex. This area has an approximately 15- to 20-foot high head scarp with ancient landslide material exposed in the scarp face.
