Petaluma, Sonoma County, California – Basalt Quarrying (Basalt) (From “The Collection of Building and Ornamental Stones in The U. S. National Museum: A Hand-book and Catalogue,” by George P. Merrill, Curator, Department Lithology and Physical Geology, in Report of the United States National Museum Under the Direction of the Smithsonian Institutions For the Year Ending June 30, 1886, pp. 438.

“Basalt. This rock differs from diabase only in point of geological age, being a product of post-Tertiary eruptions. It is, as a rule, less perfectly crystalline, still retaining portions of its glassy magma, and the surfaces of the flows are often less compact owing to their having been exposed to atmospheric agencies for a shorter period, and consequently having suffered less erosion. Owing in great part to the fact that basalts occur in this country only in western and more recently settled portions, as do also the andesites and rhyolites, they have been heretofore but little utilized. There would seem, however, no reason for excluding the rock from the list of available building materials in those regions where it occurs in such forms as to be accessible. At Petaluma, Bridgeport, and other places around the bay of San Francisco there lie immense sheets of this rock, but which are worked now (circa 1886) only for paving materials. Like the andesites and rhyolites the basalts will not polish, and their colors are such as to exclude them from all forms of interior decorative work.”

"…In the sixties quarries were opened, on Angel Island in San Francisco Bay to furnish a bluish sandstone, and near Petaluma in Sonoma County for the production of basalt. During the eighties and nineties light-brown sandstone was quarried at Benicia in Solano County, and near San Jose in Santa Clara County….”

“Hein Brothers Basalt Rock Company. The Hein Brothers pit, owned by Mark Hein, is at Haystack Landing on U. S. Highway 101 east of Petaluma. It is close to the old Petaluma Rock Quarry which formerly produced paving blocks and crushed rock.*

(Page 107, footnote 96: California State Mining Bureau, Sonoma County: California Min. Bur. Rept. 14, p. 361, 1915.)

“The Hein Brothers pit was first opened in August 1925 on a basalt flow 100 feet thick which caps a small hill. Material near the top and bottom is scoriaceous and grades inward to a black porphyry which is highly vesicular. The central part of the flow is a fine-grained tough basalt.

This pit has a face about 50 feet high. Thirty-foot holes are drilled into the toe, and when these are blasted, the upper part of the face caves. Two trucks which are loaded by a steam shovel carry the broken rock to the primary crusher which is just below the level of the pit floor. The crushing and screening plant, which is flexible enough to meet the specifications of any order, is located on the hillside above the highway. Equipment includes two trommels to remove fines from the feed to the secondary crushers which are cone crushers, double-decked vibrating screens, and crushing rolls. Belt conveyors and one bucket elevator are used.”

“Petaluma Municipal Rock Crusher, Conway Brothers, Petaluma, owners; City of Petaluma, lessee. This quarry near the west end of B street, was opened up and equipped by the city in January, 1910, under a lease, with privilege of removing plant at termination of lease. The rock, which is a black, close-grained basalt with some olivine and augite phenocrysts, occurs somewhat fractured, producing angular blocks up to three feet across. This quarry is worked only during the summer months. The product is screened to No. 1, No. 2, and No. 3 sizes and ‘dust.’ Electric power is used.

“The following is an extract from the report of F. B. Singley, city auditor of Petaluma, for the fiscal year 1912-1913:

“‘The rock crusher account from the beginning (January, 1910) to June 30, 1913. Summary as follows:

Debit:

Plant and tools to June 30, 1913: $11,458.75

Operating expenses to June 30, 1913:

Labor, $16,637.25
Supplies, $3,398.32
Power, $1,192.05
Royalty, $1,654.21

Credit:

Crushed rock sold to June 30, 1913, 22,387.4 cubic yards for: $22,124.96.

(balance) $1,356.51

“‘Against this adverse balance of $1,356.51 in the operating expenses: The city has used on her streets 5,009.2 yards; and there were in the bunkers June 30, 1913, 480 yards; a total of rock crushed, 27,876.6 yards; which cost exclusive of the plant, 84 ¼ cents per yard.

“‘The 22,387.4 yards sold brought 98 4/5 cents per yard; and the total used by the city and on hand of 5,489.2 yards, cost the city $1,356.51, or 24 ¾ cents per yard, exclusive of the plant.

“‘Previous to the installing of city crusher, the city and contractors paid $1.25 per yard for rock.’”

“Petaluma Rock Quarry (Cronin; also Mt. Pisgah), P. Cronin, Petaluma, owner; E. B. & A. L. Stone, 401 Phelan Building, San Francisco, lessees; F. L. Marty, superintendent at quarry. One time leased to Union Construction Company. This quarry in Sec. 3, T. 4 N., R. 7 W., 1 ½ miles south of Petaluma, was opened up in 1864 (10 th U. S. Census Report, Vol. X, Pt. 3, p. 279). It is at tidewater on Petaluma Creek (one time called Rudesill’s landing), and at McNear’s spur on the Northwestern Pacific. The rock is basalt with fine, white feldspar phenocrysts.

“Previous to 1890 this quarry was worked for paving blocks, but at present solely for crushed rock. In the quarry face the material is shoveled to cars and trammed to the screen which takes out the clay; then by gravity tram (in balance) to crushers (see photo No. 164). From this point a belt conveyor carries it to the revolving screen, four sizes being made: 5/16, 3/4, 1 1/4, 2 inches. A 30 h.p. electric motor dump-car of 4 cubic yards capacity transfers the product to the various storage bins. The plant has a capacity of 7000 tons per month, and the bunkers will hold 2000 tons of rock.

Photo No. 164. Plant at Petaluma Rock Quarry (E. B. & A. L. Stone Company), near Petaluma, Sonoma County, California.

“A new quarry face was being started (October, 1913), at the crusher level, which will do away with the gravity tram above. Nine men were at work, but 28 are required when in full operation. This quarry in 1913 supplied rock for the State Highway near Ukiah.

Salt Point State Park - Quarry, presented by the California Department of Parks and Recreation. (The following quotation is taken from the web site.)

Sandstone and Tafoni

”Ever wonder where the streets of San Francisco came from? Sandstone from Salt Point was used in the construction of San Francisco 's streets and buildings during the mid 1800's. If you look closely at the rocks at Gerstle Cove, you can still see eyebolts where the ships anchored while sandstone slabs were loaded onboard. Quarried rocks can still be seen scattered along the marine terrace north of Gerstle Cove. Look for the drill holes along the edges of the rocks that were used to separate the large rocks into smaller slabs.”

  “Hutchinson Ranch Quarries (Borg, Oleson, Annadel, Flinn & Treacy), Thomas Hutchinson, Santa Rosa, owner. There are several quarries on this property east of Santa Rosa. E. and J. B. Laurent, of Kenwood, are operators on the Annadel group, shipping via Annadel siding on the Southern Pacific Railroad; while Flinn & Treacy, of San Francisco, have the Borg or Oleson quarries, shipping from Oleson siding. The quarries are at an elevation of about 800 feet. There are 3850 acres in the property, of which about 1000 acres have stone suitable for quarrying. The rock is principally a dark gray andesite; but grading in part to a black, fine-grained basalt. There is also some vesicular material.
  
  “Borg first opened up the Oleson quarry about 1893. Flinn & Treacy bought 15 acres of this which they worked out and they are now operating on a royalty basis on the west end of the ranch. They made an average of over 250,000 blocks per year, for 12 years up to the beginning of 1913; but when visited (October, 1913) there were only three men employed.
  
  “Laurent Brothers have been working the Annadel quarries for about seven years, previous to which they were about 15 years on the Wymore property at Melitta. During 1912 they shipped 200,000 blocks per month for several months, but were idle in 1913.

Santa Rosa (southeast of) Sonoma County, California – the A. B.

Weaver, California State Division of Mines, September 1949) (Used with permission, California Department of Conservation, California Geological Survey.)

“A. B. Siri Pit. The A. B. Siri pit is located just to the east of the Petaluma Hill road near the Steuben School, 4 ½ miles southeast of Santa Rosa. This operation, which is less than 2 years old, produces crushed rock from a flow on the southwest flank of Taylor Mountain. The lava, which is 150 feet thick, lies between tuff beds. The underlying tuff is sandy and contains partly rounded cobbles up to 2 inches in diameter. It is a hard, bluish, asphanitic rock which is cut by joints spaced so closely that sound pieces greater than a foot in diameter are uncommon. The wider cracks are filled with shaly brown material; fine cracks are stained sulfur yellow and are commonly lined with dendritic manganese.

“Blasting is seldom necessary. Formerly several benches were maintained with bulldozers which pushed material downward from bench to bench. Now one bulldozer scrapes the rock from the top to the edge where it falls to the pit floor, and a second bulldozer brings it to the feed bin. A portable plant has been installed consisting of a belt feeder, grizzly, jaw crusher, and shaking screen. Oversize from the screen is passed through rolls and screened again. the product is used for paving and grading.”

Sonoma County, by W. A. Goodyear, Geologist and Assistant in the Field.

“Going easterly from Santa Rosa, at Appleby’s Saloon, some two miles from town, we strike a range of hills which run thence some five or six miles northerly, and seem to consist entirely of basalt. Immense quantities of street-paving blocks have been obtained from both sides of this range along its entire length. Near its northern end, on the lower slope of the higher mountains northeast of it, and about six miles from town, there are also very extensive block quarries....”

“....Altogether, this region, some six or seven miles in length, has probably furnished several millions of street-paving blocks.”

Sonoma County, by W. A. Goodyear, Geologist and Assistant in the Field.

“About one mile south of Appleby’s, and some three miles from town, there is another locality which has yielded a very large quantity of blocks. But the rock here is not basalt. It is a fine-grained, stratified, porphyritic, dark gray trachyte. Near these block quarries the same kind of rock has been quarried to some extent for curbing stones, and slabs, or blocks of it eight to ten feet long by one foot to eighteen inches wide, and six to eight inches thick, are here easily split out with plugs and feathers. This rock, though somewhat vesicular, is nevertheless hard and strong, and would make a fair quality of building stone. Altogether, this region, some six or seven miles in length, has probably furnished several millions of street-paving blocks.”

“Titania Quarry (Clute; Swank; also “Santa Rosa Bank”). P. Maroni, 925 Ripley street, Santa Rosa, owner. This quarry, 2 miles east of Santa Rosa, was first opened up in 1885 by Clute and, up to seven years ago when the present owner took it over, produced only paving blocks and building stone. At present (circa 1914), besides crushed rock, some curbing and small dimension stone for buildings are turned out. Stone for the La Rose Hotel in Santa Rosa came from this quarry. The rock is a dark gray andesite. A 25 h.p. gasoline engine is used and fourteen men are employed. The crushing plant has a daily capacity of 40 cubic yards. The crushed rock is sold at $1.60 per cubic yard in Santa Rosa and $1.10 at the plant. Gravel from Santa Rosa Creek on the same property is also sold by Maroni.

Sebastopol, Sonoma County, California – the Stony Point Quarry (Trachytic Lava) (From The Structural and Industrial Materials of California, Bulletin No. 38, California, State Mining Bureau, San Francisco, California, 1906.)

“Stony Point Quarry; Petaluma and Santa Rosa Interurban (electric) Railroad, owner; R. J. Evans, superintendent; located on the railroad, about 9 miles south of Sebastopol. The rock is a trachytic lava, showing occasional flow structure, with small pebble inclusions, and occurs as a capping on a low hilltop. The drainage on either side of the hill has eroded down through it. When green, the stone breaks with a fairly even face and is easily dressed, resembling the San Jose sandstone so much that it is erroneously called sandstone by people of Sonoma County. When seasoned, it becomes nearly white in color, very hard and refractory. The stone stands well, as is shown by the Phoenix Building, in Petaluma, which was erected about 1862. It has been used in other buildings in Petaluma, and recently the Carnegie Library, which is now nearing completion (November, 1904).

“At present the quarry face is being opened with a view of later taking out building stone for shipment to bay points by rail and water. Both electric and steam power are available. About 85 men are employed, and the quarry is operated day and night, the rock being used principally for ballast on the railroad bed.

“On the north side of the same hill, P. Maroni has been endeavoring to take out some suitable stone for the erection of the new bank building in Sebastopol. The stone occurs in pentagonal columns averaging about 5 feet in thickness, dipping N. 30° E. at an angle of about 70°. On account of cross fractures or seams, it is very difficult to obtain dimension stone more than 5 or 6 feet in length. Another small opening near the crest of the hill shows similar columns.”

“Fairville Quarry and Gravel Company. At the pint marked 'Quarries' north of Sears Point on the Mare Island quadrangle the Fairville Quarry and Gravel Company operated a pit from 1907 to 1910.* Volcanic breccia and lava flows here dip at about 30° SE. The upper layers are a gray porphyry with many feldspar phenocrysts, some eighth of an inch long. Joints are so numerous that sound pieces greater than about 2 feet in diameter are rare. There is a strong suggestion of columnar jointing. The underlying rock which the quarry penetrated is very porous, amounting to an open network of feldspar crystals containing angular inclusions an inch or two in size of both porphyry and basalt. In places a canary yellow material fills the interstices; in other places they are filled with a brick-red material.”

“Natomas Consolidated of California (formerly Schocken), Natomas Consolidated of California, Alaska Commercial Building, San Francisco, owner. This quarry (or rather series of quarries) is on a steep hill ½ mile north of Sonoma; elevation 400-500 feet (U.S.G.S.); and was first opened up in 1876. In 1880 it was bought by S. Schocken who operated it up to 1909, when the present owners took it over. About 1888, an average of 100,000 paving blocks per month were shipped from here, with 60 men at work. Some curbing and small dimension building stone have also been produced. Only two men were working, October, 1913.

“The rock is a gray andesite, some of it having abundant, white feldspar phenocrysts. The surface of the hill near the summit is extensively potholed, with openings from a few square feet to one over an acre in extent and with a 100-foot bank. It is stated that the Natomas bought the property as a source of supply for crushed rock, as the spall piles are numerous and extensive. This feature has not yet been developed. In the early days of this quarry before the advent of the railroad, the paving blocks were hauled in wagons to the Embarcadero on Sonoma Creek, where they were loaded on barges.

Weaver, California State Division of Mines, September 1949) (Used with permission, California Department of Conservation, California Geological Survey.)

“Candy Rock Quarry. A mile and a half up Nuns Canyon from State Highway 12 in sec. 3, T. 6 N., R. 6 W., is the Candy Rock or Nuns Canyon quarry, owned and operated by V. O. Campbell. Highly colored building blocks, gray, green, and pink, are produced very occasionally by the owner and a helper as the demand for them arises. The rock, a blocky altered rhyolite heavily stained with limonite along the joints, is somewhat softer than steel, and banded, although it does not split along the bands. In general the blocks are pink at the center with a very irregular outer zone of gray or green suggesting alteration which worked in from the joints. The blocks are cut by cracks perhaps 1/10 of an inch wide in which tiny quartz crystals and cubes of pyrite, partially altered to limonite, have formed. In places the rock is spotted with blebs of opal, while in others there are small chalky looking anygdules partially filling rectangular openings. Here and there an irregular calcite veinlet as much as 3/8 of an inch wide cuts the rock.”

“Schocken Quarry; S. Schocken, Sonoma, owner. This is the largest quarry being operated in the vicinity of Sonoma, and is located 1 ½ miles north of the town. The rock occurs in boulders of various sizes and shapes, ranging from 1 to 20 feet in cross-section. About ten men are at work getting out gutter rock and paving blocks, and they average about 10,000 blocks a month.

“This and nearby quarries have been worked for many years, and great dumps of chips cover the hillsides. This apparent waste rock would, with very little crushing, make a very good material for macadam or concrete purposes.”

  “Vallejo Estate Quarries. Mrs. L. V. Emparon, Sonoma, owner; H. C. Manuel, lessee. There are several quarry openings on this property ½ mile north of Sonoma. The series of rocks here shows all gradation stages from a fine-grained black basalt through andesite and vitrophyre to tuff. Paving blocks are made from the basalt by Manuel, who had (October, 1913) seven men at work (previously 15 to 20); while the other rocks have been used locally for building stone. As has already noted, the city of Sonoma has a small rock crushing plant here to utilize the spalls from block-making.

Weaver, California State Division of Mines, September 1949) (Used with permission, California Department of Conservation, California Geological Survey.)

“Valley of the Moon Quarry. The Valley of the Moon or Cabrol quarry is one of the largest producers of ‘flagstones’ in the area and has operated more or less continuously since 1928. It is owned by S. Cabrol but leased and operated by R. J. Johns. The quarry is south of Trinity Road half a mile from State Highway 12 in sec. 10, T. 6 N., R. 6 W. The rock quarried is a blue-gray banded rhyolite which readily splits into layers 1 or 2 inches thick, along parting planes formed by tiny elongated vesicles. The layers are nearly horizontal and almost parallel, although near the edges of the quarry they become somewhat distorted. This banded rhyolite seems to occur as large irregular masses in the volcanics. In quarrying, occasional blasting with light charges of slow dynamite, is necessary. Blocks are pried out and hauled onto the quarry floor where they are split by hand.”
