Eagle Rock, at the east end of the Eagle Rock Valley, which can be 

 seen from the railroad in the vicinity of West Glendale, is an old 

 landmark composed of a locally hardened mass of Miocene (Mon- 

 terey) conglomerate. The '^ eagle" on the side of the rock is caused

 The city contains 3,000 or 4,000 pei-sons, employees of the picture 

 company, and a zoo comprising several hundi-ed wild animals. 

 The Monterey beds on the north flank of the SantaMonicaRanse 



south of the railroad, are intruded by basalt dikes and associated 

 with flows of the same lava. Overh-ing the Monterey, and deposited 

 later than the basalt flows, is the Fernando formation, consisting of 

 conglomerates, sandstones, and soft shales, which dip toward the 

 valley. The Fernando beds also flank the eastern extremity of the 

 San Fernando Hills north of the San Fernando Valley. This forma- 

 tion is full of fossil shells and other marine organisms, which indicate 

 upper Miocene, Pliocene, and Pleistocene age. 



About 3 miles west of Burbank the raihoad crosses Tujunga (too- 

 hoon'ga) Wash, which marks the underground channel of a tributary 

 to Los Angeles River. This phenomenon of underflow is character- 

 istic of the arid and semiarid regions of the Southwest. Several 

 mountam streams unite m formmg Tujunga River, which debouches 

 from the mouth of a canyon mto Tujunga Wash. The water immedi- 

 ately smks out of sight and flows tlirough coarse gravels and sands 

 under the plam until it reaches the hard rocks i
