Annual report of the State Mineralogist for the year ending ... . lity in LosAngeles County is at Pico Canon, of which some description is given inthe Fourth Annual Report of the State Mineralogist. The wells are situ-ated in and about the head branches of Pico Canon, which runs northerlyout of the San Fernando Range of mountains to the Santa Clara all, something over thirty wells have been drilled here to various depths,ranging from five hundred to two thousand three hundred and thirty product is a green oil whose gravity is from 40° to 42° B. There ishere a storage tank of twenty thousand barrels capacity. The oil fromthe different wells is all mixed together and piped from here to Newhall,whence most of it goes by rail to the refinery at Alameda. There is onlyone flowing well; all the rest are pumping wells, though some of themwould flow more or less if they were not pumped. As to the flowing well, the experiment of pumping it has also been tried,but this did not increase its production sufficiently to justify the expense. 80. WELLS AT PICO CAXON. All the wells produce also some gas, the whole of which is utilized underthe boilers, except in the case of two wells, where there is a surplus, whichescapes from two iron pipes into the open air and burns with constantflames from two to four feet long. Nearly all the oil is found in a light-gray, porous sandstone, and thedeepest wells have none of them reached the bottom of this coarsest grains in the drillings from this rock range from one thirty-second to one sixteenth of an inch in diameter. The rocks here have been greatly plicated, crushed, and broken, andthere is either a sharp anticlinal fold, or else a large fault of unknown mag-nitude, running for some distance nearly east and west, on the north sideof which the rocks dip to the north with an average pitch of about 70°, andon the south side of which they dip to the south at steep but varying the south of this line
