Rocklin, Placer County, California – Granite Quarries at Penryn (circa 1891) (from transcription of Stones for Building and Decoration, by George P. Merrill, Curator for Geology in the United States National Museum, J. Wiley & Sons, 1891, pp. 180.
“...As early as 1853 a granite quarry was opened in Sacramento County, and since then others have been opened and systematically worked in Penrhyn and Rocklin in Placer County. The Penrhyn works are some 28 miles east from Sacramento on the line of the Central Pacific Railroad. The first quarries were opened in 1864, and are now said to cover some 680 acres at Penrhyn and Rocklin,* the latter point being some 6 or 8 miles distant from the former in a westerly direction.
(* Footnote: Samples of stone said to be from Rocklin, and which the writer has examined, are rather quartz diorites than true granites.)
“The rock varies in color from light to dark gray, one variety, which contains both hornblende and biotite, being almost black on a polished surface. They are, as a rule, fine grained, and take a good polish. Blocks more than 100 feet long, 50 feet wide, and ten feet thick have been quarried out and afterwards broken up.
“The Penrhyn stone is designated a hornblende granitite by Jackson,* who gives its mineral composition as quartz, orthoclase, plagioclase, hornblende, and biotite, with microscopic apatite and magnetite. Submitted by the above authority to the action of a carbonic acid gas solution, a sample of this stone lost 0.05 per cent in weight; by disintegration in acid fumes it lost 1.09 per cent. In this latter treatment every mica scale on the surface of the exposed fragments bleached to a pearly whiteness. The iron was dissolved out, staining the rock slightly, while the feldspar grains became a trifle duller in lustre. On being heated in a muffle to somewhat above a bright redness, the stone developed a complete network of deep-seated cracks, and after emersion in water could be readily crushed to powder in the hands.
(* Footnote: Eighth Annual Report State Mineralogist of California. 1888.)
“The Rocklin stone is described by the same authority as a fine-grained white stone, carrying abundant small scales of mica and occasional granules of pyrite. The composition is given as eesentially the same as the Penrhyn stone, but that muscovite replaces the hornblende. Submitted to the same tests as above the stone lost in the carbonic acid gas solution 0.1 per cent; and by decomposition and disintegration in the strong acid fumes 0.68 per cent. In this, as in the last case, mica scales bleached white, and the rock became slightly stained. Heated in the muffle the stone behaved like the Penrhyn granite, though not cracking quite so deeply; it, however, could be readily crushed to powder after immersion. Reports on crushing strength and ratio of absorption of these stones, and also that of a very similar granite from Mount Raymond is (sic) Fresno County are given in the table, on p. 404....”
"Rocklin is the principal granite-producing point in the Sacramento valley. The first quarry was opened in 1863, and the stone was used in construction work on the Southern (then Central) Pacific Railroad. Brigham & Hawes operated the same quarry later and took out stone for the State Capitol at Sacramento. This quarry, after changing hands several times, came into possession of Degan & Brady, who took out the stone for the Hibernia Bank and the Crocker Building, San Francisco, since the completion of which this quarry has been idle.*
(* Historical information furnished by A. W. Grindell of Rocklin.)
"The Rocklin quarries are comparatively close together. They occur on an area probably less than a mile square, on a gently rolling plain, which borders the railway and extends from 1 to 2 miles on each side to the bottom of a bluff 200 feet or more in height, which marks the border of the upland mesa.
"In most places over the quarry area the granite occurs at the surface. In some places there is a very light soil-covering, and in others the surface is covered with huge residual boulders. The stripping is very slight over the entire area.
"In going northward through Penryn and Newcastle, the Rocklin plain becomes narrower and gradually disappears in the low rounded granite hills, which become higher and more rugged as one follows the railway north and east of the Sierras.
"The granite area is many miles in length and width, but the quarries above mentioned are the only ones in the area in Placer County that have more than local importance.
"The Rocklin stone is a biotite granite, bordering on monzonite. It contains some plagioclase and a little augite, but the prevailing feldspar is orthoclase, and biotite is in excess of muscovite. Some of the orthoclase shows a zonal structure and other portions show partial disintegration, most marked in the central portions of the crystals. In places on the weathered surfaces the biotite is partially disintegrated.
"There are fifteen quarries in operation (August, 1904), and several others idle. Most of the quarries are small, employing from 3 to 10 men. The largest quarry is working 33 men, but at times employs as many as 50. Most of the small quarries are operated by Finns, Russians, and Italians. The following is a list of the operators in August, 1904, as nearly correct as could be obtained. Some of the men speak very broken English, if any at all, and a few of the names may not be spelled correctly:
(1) The Rocklin Granite Company, I. L. Delano, president, Builders' Exchange, 106 Jessie street, San Francisco; (2) Adolph Penru; (3) August Martin & Co.; (4) Band Granite Company; (5) Nikolai Naykki; (6) John Pisili; (7) Holowen & Co.; (8) A. O. Wickman; (9) John Kannasta; (10) Henry Hebuck Granite Company; (11) Pete Johnson; (12) Matt Johnson; (13) Oskar Kesti; (14) John Mantyla; and (15) Janhiala Company.
"Nos. 1 (the Rocklin Granite Co.) and 14 (John Mantyla) are the largest quarries. The Allen quarry, owned by Myers, now idle, has been quite productive in the past…."
"Much of the work in the different quarries is done by hand. The larger quarries are supplied with steam drills and surfacing and polishing machines, but in the smaller quarries the drilling, surfacing, and polishing are done by hand. There are nineteen steam-power derricks, mostly at the larger quarries, and fourteen horse-power derricks used at the smaller quarries. Blasting is carried on to some extent, but most of the stone is split with wedges, or by use of plugs and feathers. Each of the quarries has a railway spur to the quarry, all connecting with the Southern Pacific Railroad at Rocklin."
At the time the field work was done for this report in October and November, 1915, this quarry was listed as being idle.

"The most northern and the largest quarry in the Rocklin area is owned by the Rocklin Granite Company. Like all the other quarries in this locality, it is in a rectangular pit, sunk in the surface of the rolling plain. The opening is about 100 feet deep, 100 feet wide, and 250 feet long. The rock has a remarkably straight grain and regular cleavage. Curbing slabs, from 10 to 20 feet long, are split with surfaces almost as regular and even as those cut with saws. Numerous slabs up to 16 by 20 feet surface, and from 10 to 12 inches thick, have been removed from the quarry. These large slabs, like the smaller ones, are nearly all split from the ledge by use of plugs and feathers. The large slabs are used in construction of cemetery vaults. The quarry is well equipped with machinery for handling and dressing the stone. It is provided with large derricks and steam hoists, an overhead steam traveler in the cutting sheds, and several polishing and surfacing machines. Compressed air is used in the cutting shed for drilling and surfacing. Steam and hand drills are used. The quarry was opened in 1877 by Mr. Marine. From 1878 to 1889 it was operated by Mr. G. Griffith. Since 1889 it has been operated by the Rocklin Granite Company. It has furnished large quantities of building and ornamental stone in that time…."
