160 OIL DISTRICTS OF SOUTHERN CALIFORNIA. 
and many of the once-productive wells are now abandoned. During 
the past year (1905) the council of the city of Los Angeles took cogni¬ 
zance of this fact, and in order to do away with the nuisance of 
abandoned wells and pumping plants in a thickly populated residence 
quarter outlined certain districts within which all traces of the oil 
industry are to be removed within a certain period. This policy, if 
carried out, will eventually result in the abandonment of the city 
fields, so that probably in only a few years the thickly set derricks 
which now extend through the northern part of the city will be a 
thing of the past. 
EASTERN FIELD. 
LOCATION. 
The eastern field comprises that portion of the productive oil ter¬ 
ritory of Los Angeles which lies between the Sisters’ Hospital grounds, 
corner of Sunset boulevard and Beaudry avenue, on the west, and the 
Catholic cemetery, corner of Cottage Home and Buena Vista streets, 
on the east. Its northern boundary is a line running from the north¬ 
ern part of the hospital grounds eastward to a point on the western 
line of the cemetery 600 feet north of Buena Vista street; its southern 
limits are Alpine street from the hospital southeastward to Figueroa 
street, and thence a line slightly north of east to the southwest corner 
of the cemetery. This area is nearly three-fourths of a mile long, 
with a maximum width of about 1,000 feet near the middle and a 
minimum of less than 400 feet at the ends; it contains approximately 
one-eighth of a square mile. 
TOPOGRAPHY. 
The eastern field lies on the southwestern flank of the Elysian Park 
hills, along the southern faces of the two well-developed minor ridges 
which are separated by Chavez Ravine. The topography, however, 
appears to have no connection whatever with the structure of the 
field or the extent of the productive zone, the line of wells forming an 
approximately straight belt from the low southwestern slope of the 
western ridge at the Sisters’ Hospital, up over the face of this same 
ridge, down into and across the mouth of Chavez Ravine, and east¬ 
ward over the lower portion of the eastern ridge. 
GEOLOGY. 
All the formations from the Puente sandstone to the Fernando 
beds are involved in the geology of the eastern field. North of the 
field and forming the bulk of the Elysian Park hills is the thick- 
bedded gray to light-j^ellow and rusty-brown sandstone of the Puente 
formation. This outcrops along some of the park roads and is excep¬ 
tionally well exhibited on Buena Vista street east of the field and
