Three faults in Griffith Park, converging along the Lower Beacon Trail

Figure 13. Digital Elevation Model of the faults opposite the Lower Beacon Trail in Griffith Park. The unnamed faults in the top-right are from the 2010 California fault activity map (Seamless Data Warehouse, 2010 (digital elevation model image); Google Earth, 2007 (inset image); Jennings & Bryant, 2010; Jones et al., 1990; Neuerburg, 1953; Dolan, Sieh & Rockwell, 2000 (fault data)). The mountains lying to the north of the Verdugo Fault are the Verdugo Mountains and past these are the San Gabriel Mountains. Highland Park is south of the Eagle Rock Fault, and just north of the inferred extension of the Raymond Fault. The hills in the center of the image, just below the dashed lines of the Eagle Rock Fault, are Glassell Park. Mount Washington is the elevated area adjacent to the south of this. The Los Angeles River can be seen meandering through the center of the figure from NW to SE. The City of Los Angeles lies about where the “2 mi.” rests on the page. Northwest of Los Angeles is Elysian Park and Silverlake, and northwest of here is Griffith Park, the easternmost extension of the Santa Monica Mountains. The white rectangle represents the satellite image inset. Of the three faults, the one labeled Fault 3 is the most impressive. Looking out to the east, the sloping edge of Adams Hill lies directly opposite, and is very clear. This edge forms the northeast boundary of the high terrain called Glassell Park, and Highland Park lies beyond. Fault 3 perhaps connects with the Eagle Rock Fault, which runs through the foothills just to the north of that city. It does not seem to connect with the Raymond Fault, which runs more southerly, through Mount Washington.

Location of the fault intersetion: 34.127886, -118.275178
