  • Chatsworth (west of), Los Angeles County, California - the Chatsworth Park Quarry (Sandstone) (From The Structural and Industrial Materials of California, Bulletin No. 38, California, State Mining Bureau, San Francisco, California, 1906.)

    "Chatsworth Park Quarry, 200 acres in Sec. 13, T. 2 N., R. 17 W. S. B. M.; California Construction Company, 324 East Market street, Los Angeles, Owner. About 1 miles west of Chatsworth, a station on the Southern Pacific Railroad. The quarry is connected by a branch line with the main road.

    "The stone is rather heavily bedded arkose sandstone. Near the surface it has a tawny color, but when fresh is of a bluish-gray color. This weathering takes place to irregular depth, but the line demarcation between the weathered and fresh stone is very distinct. The stone is moderately fine-grained. When quarried for dimension stone it can be split regularly along the run, but when quarried for large blocks, as is done in this quarry for the substructure of the San Pedro breakwater, it breaks along uneven surfaces. It resists exposure to the atmosphere satisfactorily. Near Garvanza is a church (Holy Angels), built in 1887, of the tawny-colored stone, showing no signs of deterioration. The Courthouse in San Bernardino, the Public Library in Santa Ana, and the California Club in Los Angeles are all built of the tawny variety of this sandstone, taken from near the surface. At the land end of the Southern Pacific Railroad pier at Santa Monica some of this sandstone has been used for rip-rap. Below the level of high tide, where moistened by seawater, it is quite hard, but above high-water line the exposed stone is rather soft and somewhat disintegrated.

    "The blocks that form the San Pedro breakwater are broken down by churn-drilling (three men to the drill) rows of holes, having an average depth of 25 feet, with 20 feet face, and blasting with black powder, tamping solid without an air chamber above the charge. It is estimated that of the rock thus broken down 20 per cent is debris, under 100 pounds, thrown over the dump; 15 per cent is small blocks, from 100 to 1000 pounds; 20 per cent is blocks from 1000 to 4000 pounds; and 45 per cent large blocks over 4000 pounds. (See sketch of front elevation of quarry.)

    Ill. No. 61. Chatsworth Park Sandstone Quarry, Los Angeles County.

    "The quarry is equipped with four steam derricks, using oil as fuel. Capacity, from 500 to 700 tons per day of random stone of large size for San Pedro Breakwater. About fifty men are employed."

    • Chatsworth (west of), Los Angeles County, California - Chatsworth Park Quarry (Sandstone) (Excerpt from Report XV of the State Mineralogist, Mines and Mineral Resources of Portions of California, Chapters of State Mineralogist's Report Biennial Period 1915-1916, Part IV. Los Angeles County, Orange County, Riverside County, California State Mining Bureau, 1919, pp. 465-589. Used with permission, California Department of Conservation, California Geological Survey.)

      "Chatsworth Park Quarry: (see Bulletin 38, p. 128). This property comprises 160 acres in Sec. 13, T. 2 N., R. 17 W., S. B. M. It is about 1 miles west of Chatsworth station, on the Southern Pacific Railroad and was formerly connected by a spur track with the main road. The locality is at the northeast end of the Simi Hills, a rugged range of sandstone strata, folded and faulted, their dip being plainly visible from the southward.

      "The stone of the quarry is arkose or feldspathic sandstone, rather fine-grained and heavily bedded. When fresh it is bluish-gray, but near the surface it weathers to a tawny color. This weathering extends to an irregular depth, but the demarcation between the weathered and fresh stone is very distinct. It is said, that when quarried for dimension stone, it can be split regularly along the run, but that when quarried for large blocks, as done for the substructure of the San Pedro breakwater, it breaks along uneven surfaces. As shown by some samples it usually resists exposure to the atmosphere in a satisfactory manner.

      "Near Garavanza, on N. Avenue 64, is the Church of the Angeles, built in 1887, of the tawny-colored stone, which as yet shows no signs of deterioration (circa 1915).

      "In Los Angeles, corner of Fifth and Hill streets, is the house of the California Club, built of an olive-gray stone from the Chatsworth Quarry, but much stained by the leaching of soluble salts. Christ Episcopal Church, corner Twelfth and Flower streets, Los Angeles, is constructed of Chatsworth sandstone and also the city police station and jail on First Street, near Hill, and the Southern California Edison Company's building, East Fourth Street, near Main. A few private residences also have been built of this stone. At the shore end of the Southern Pacific Railroad pier at Santa Monica, some of this stone was used for rip-rap. Below high water level, where kept moistened by seawater, it remains quite hard, but above high-water mark, the exposed stone is rather soft and somewhat disintegrated.

      "The geologic age of the rock in this quarry is Upper Cretaceous or Chico, as mapped on Plate III of the folio accompanying Bulletin No. 69 of the State Mining Bureau.

      "The quarry was opened by the California Construction Company, which (about 1900) took the contract for building the San Pedro breakwater. At present the property is held by the Los Angeles Trust and Savings Bank as trustees for creditors of the California Construction Company, which has forfeited its corporate rights through nonpayment of taxes, but it is now represented by the president, W. N. Hamaker, care of First National Bank, Los Angeles.

      "No rock has been quarried here for years, the quarry having been dismantled and its equipment and spur track removed.

      "Judging from examples of this sandstone in use, it is an important building stone, and it is to be hoped that the quarry may again be opened."

(Manuscript submitted for publication October 6, 1953.) Used with permission, California Department of Conservation, California Geological Survey.)

      "Building stone, consisting of Upper Cretaceous sandstone of the Chico formation was produced in large tonnages in the Chatsworth area in the early 1900s. (Merrill, 1919, pp. 482-483). Large blocks from the Chatsworth quarries were used in the San Pedro Breakwater, and several churches, large buildings, and private residences were constructed from this stone. Several quarries were active but all were shut down by 1915 and no subsequent activity has been reported."
