- Lakeside (north of), San Diego County, California – Lakeside
Lime and Marl Deposit (Limestone & Marl) (Excerpt from “Limestone
in California,” by Clarence A. Logan, California Journal
of Mines and Geology, Vol. 43, No. 3, July 1947, California

"Lakeside lime and marl deposit is on El Cajon Rancho, in the northeast corner of T. 15 S., R. 1 W., S.B., 3 miles north of Lakeside. The marl has a thickness of 2 to 4 feet, with a light overburden of soil. It has been used locally as soil corrective or fertilizer. According to a partial analysis quoted in past reports as having been made by the State Department of Agriculture, the CaCO3 content of the product sold was 83.7 percent.
"On Otay Mesa near Otay, a marl similar to that north of Lakeside was reported. Otaylite (montmorillonite) has been worked here extensively and possibly this was mistaken for limestone years ago."
- Lakeside (near), San Diego County, California – Andrew
Lehnberg (Granite Quarry) (Diorite) (Excerpt from Report
XIV of the State Mineralogist - Mines and Mineral Resources of
Portions of California, Chapters of State Mineralogist's Report – Biennial Period 1913-1914, Part V. "The Counties of
San Diego, Imperial," by Frederick J. H. Merrill, Ph.D.,
Field Assistant (field work in December, 1914), California State
Mining Bureau, San Francisco, California, 1916, pp. 427-634.)
"Andrew Lehnberg, of Foster, operates a quarry on El Cajon Grant, west of Foster, and about 600 yards south of the Simpson-Pirnie quarry. This is also biotite granite. He also operates a quarry of dark green rock near Lakeside, which Dr. A. S. Eakle has identified as diorite. This material is derived from boulders, no ledge having yet been opened."
"Dr. A. S. Eakle's determination of (this rock) is as follows:….
"Lehnberg, Lakeside. Hornblende-diorite. A thin section shows plagioclase predominating and scattered plates of hornblende. A few rods of biotite occur. The rock has a sprinkling of magnetite with an occasional grain of pyrite."
"San Diego Granite Works, corner Eleventh and M streets, San Diego, Fred Fickas, proprietor…It now uses stone from the Simpson-Pirnie quarry west of Foster and from Lehnberg's quarry near Lakeside (circa 1914)…."
- Lakeside (52 miles southwest of), San Diego County, California – Verruga
Marble Quarries (Marble) (Excerpt

"Verruga marble quarries are in sec. 10, T. 11 S., R. 4 E., S.B. Eight patented claims were owned by John Johnson, Escondido, in 1939. The nearest railroad point is Lakeside, about 52 miles southwest. Road improvements in late years should permit hauling of marble at much less than the former cost, which was prohibitive when the quarries were last worked from 1921-23.
Two deposits of marble, 800 feet apart and separated by mica schist, occur in an area of metamorphic rocks near granite. The western deposit outcrops for about 1000 feet striking N. 20 W. and is about 100 feet wide. The eastern outcrop is reported to be 200 feet by 1000 feet. Two quarries were opened in the twenties on the western deposit and the marble was used in several buildings in San Diego. Some work was also done on the eastern deposit. The marble is white, coarsely crystalline and of uniform texture and color. It is quite hard and can be quarried in large blocks."

- Peninsula Range of Mountains, bounding the Colorado
Desert on the West, San Diego County, California, & the
Mexican territory of Baja California - Stone Resources (Marble,
Limestone, Sandstone, & Granite, etc.) - Excerpt
from the Tenth Annual Report of The State Mineralogist For
The Year Ending December 1, 1890, California State Mining
Bureau, Sacramento: State Printing Office, 1890, pp. 899 & 906.
(pp. 899)
“...This great basin, near the mouth of the Colorado River of the West, forms one of the most extensive and important portions of the arid regions of the United States. The vast area known as the Colorado Desert, comprises all the country lying between the Colorado River on the east and the Peninsula Range of mountains on the west - a vast triangular-depressed plain, below the level of the sea for the larger portion of its surface, and comparatively destitute of verdure or of animal life.
“This remarkable region has an approximate area of twelve million acres, about one half of which lies within the boundaries of San Diego County, California, the remainder in the Mexican territory of Baja California....”
(pp. 906)
“The Peninsula Range of mountains, bounding the Colorado Desert on the west, possesses a rich variety of the choicest granite, marble, and sandstone, unsurpassed in quality for building purposes. Some of these varieties are exceedingly beautiful, but are still practically unavailable from their comparative inaccessibility.
“The surface of the desert is strewn with fragments of marble for a large portion of its area. These are worn and beautifully polished or sculptured by the drifting sand, until each is in itself a natural ornament. Da Costa, in his ‘Natural History of Fossils’ (1757), page 197, says that ‘yellow marble was more esteemed by the Romans than all other varieties.’ Some of the delicately tinted pink, yellow, and variegated marble specimens from this region would lead us to indorse the taste of these ancient connoisseurs.
“Aside from the marble and limestone so abundant in this section, we find immense quarries of red and brown sandstones worthy of entering into the construction of the finest palatial homes.
“The following are the principal species of rock found on the desert which may become useful in building construction:
Marble and limestone, in different grades.
Cement rock.
Pumice. - Abundant in the great basin.
Gypsum.
Asbestos.
Porphyry, lava, and other volcanic rocks.
Sandstone; red, brown, and gray.
Gneiss, granite, and other granitic rocks.
Dunnite. - ‘From Cargo Muchacho Mining District, San Diego County. This consists of three distinct minerals - olivine, magnetite, and micaceous mineral, unknown.’ (See Sixth Annual Report of the State Mineralogist, Pt. I, pages 32-33.)
Breccia. - Suitable for building purposes.
Clay. - A variety of clays suitable for a great number of uses, exist in large deposits of as great a degree of purity as could be desired. But little attention has naturally been given to these natural resources of our county. That these deposits will prove a source of wealth in the future cannot be doubted.”

"At Jamul, 18 miles southeasterly from San Diego, hydraulic cement was manufactured on a small scale a number of years ago. The reason commonly assigned for abandoning the industry at this point is that it is too far from the railway. The plant was designed, it is said,* to produce 200 barrels per day."

"Jamul Portland Cement Company was organized in San Diego County in 1889, to manufacture cement at a plant on Jamul Rancho, 18 miles east of San Diego (Irelan 90, p. 309).* The erection of a plant was started in 1890 (Storms 93, p. 383)** and it was finished on June 1891. It contained seven kilns and had a capacity of 150 barrels a day. The product was used for sidewalks in San Diego and according to Storms (93),** it was also sold elsewhere in southern California. The project was evidently short-lived. It was said to cost more to haul the cement to San Diego than the cost of bringing English portland cement to California by water.

“The granite from Santee is used largely for monumental work, also for building stone, and large quantities of it have been shipped to Los Angeles and other points in southern California. In monuments it resembles the widely used granite from Barre, Vt. The rock is of medium to rather dark gray color, distinctly darker than the average California granite, and of medium, even grain. It is composed essentially of bluish gray translucent feldspars and black intergrowths of hornblende, augite, biotite, and magnetite. All the minerals appear to be quite free from alteration. The rock takes a good polish, which, with its dark color, especially adapts it for monumental work.”

- Santee, San Diego County, California – the Simpson-Pirnie Granite Company (Granite) (From The Structural and Industrial Materials of California, Bulletin No. 38, California, State Mining Bureau, San Francisco, California, 1906.)
"Simpson-Pirnie Granite Company, James Simpson, president, San Diego. At Santee, a station on the San Diego, Cuyamaca and Eastern Railway, 3 miles north of El Cajon and 25 miles north of San Diego, is a granite quarry that has been operated for several years. A short railway spur extends from Santee to the quarry, which is on the north side of the El Cajon Valley. The granite is quarried by hand. The stone is a bright-colored, light-gray, biotite-augite granite, which has a reddish to brownish tint on the weathered outcrop. In some places this brownish discoloration from the oxidation of the iron extends several feet below the surface, while in other places it is a mere shell on the surface. In the middle of the quarry face is a dike-like band that shows several open vertical joint seams, but elsewhere on the face the rock is massive and almost free from open seams. It has a remarkable straight fracture, and is easily obtained in regular rectangular blocks as large as can be handled. There is comparatively little stripping to the granite mass and no expensive waste in quarrying. As the quarry is at the base of the butte, the height of the quarry face will increase as it is worked back toward the center of the hill. The stone is quite uniform in texture and color, with the exception of a few small dark blotches caused by a local segregation of the dark mica flakes. It is used largely for monuments, and for this purpose it is cut and dressed at the company's yard in San Diego and shipped in considerable quantities to Los Angeles and other points in southern California. It also makes an excellent building stone, for which it is used to some extent."

Merrill, Ph.D., Field Assistant (field work in December, 1914), California State Mining Bureau, San Francisco, California, 1916, pp. 427-634.)
For a description of the second quarry mentioned in the description above, also operated by this company, see:"Simpson-Pirnie Granite Company, James Simpson, president, Peter C. Pirnie, secretary. Office and works. Two quarries are worked. One is near Santee station on the San Diego, Cuyamaca and Eastern Railway, 25 miles from San Diego in the east side of the hill south of the station. The property comprises 49 acres.
"The granite is quarried by hand. The stone is a bright-colored light gray grano-diorite with a reddish to brownish tint on the weathered outcrop. In some places this discoloration from the oxidation of the iron extends several feet below the surface, while in others it is merely superficial. For the most part the rock is massive and almost free from open seams. It has a remarkably straight fracture, and is easily obtained in rectangular blocks as large as can be handled. There is little stripping and no expensive waste in quarrying. The stone is quite uniform in texture and color, with the exception of a few small blotches caused by local segregation of dark mica flakes. It is largely used for monuments, and for this purpose is cut and dressed at the company's yard in San Diego and shipped in considerable quantities to Los Angeles and other points in southern California. It also makes an excellent building stone, for which it is used to some extent. The annual product amounts to 5,000 cubic feet of dimension stone, 200,000 of paving blocks and 1,500 tons of riprap."
"Dr. A. S. Eakle's determination of (this rock) is as follows:….
"Pirnie-Simpson, Santee. Granodiorite. A thin section shows much triclinic feldspar as well as orthoclase, a small amount of quartz, biotite and hornblende."
(This quarry was in operation ca. 1914.)

“In the Temecula Cañon itself there are now two quarries, one about two miles and the other about three miles below the railroad station. From the lower one of these quarries, a block was lying at Temecula Station on November tenth, which will dress into a thirty-inch cube, of a dark gray and fine-grained syenite without a flaw. This block is to form the basis of a monument of some sort at San Diego. The rock contains a little magnetic iron. But it appears to be very hard and strong, and will probably take a beautiful polish and prove to be very durable.”

“At one locality within this belt, and on about the middle of the south half of Section 28, of Township 5 south, Range 4 west, S.B.M., there is a considerable body of hard, dark blue, compact limestone. Here, two small kilns have been built, and some of the limestone burned, producing, it is said, a very good quality of lime. A company is now being organized for the purpose of manufacturing hydraulic cement by mixing this lime in certain proportions with the clays that occur in such large quantities among the hills northwest of Elsinore.”

“At Temecula Station there was lying (November 10, 1889) a considerable quantity of dressed street paving blocks of a moderately coarse-grained, light-gray granite, which is stained more or less yellowish in places by oxide of iron.
“The rock seems to be hard and durable, and splits and dresses well. It has been used for paving-blocks in Los Angeles and San Diego, all for street curbing in both those cities, and also in San Francisco. The quarry from which it comes is situated in the foothills on the southwest edge of the valley, about half a mile southeasterly from the head of Temecula Cañon. And here it may be well to correct an error which occurs on page 174 of the seventh annual report, lines five to eight from bottom of the page, where it is stated that Elsinore Lake, in times of heavy rains, ‘discharges its surplus waters into Temecula Cañon, a branch of Temescal Creek, which runs to the Santa Ana River.’ The writer was led into his mistake about the name of the creek by an erroneous map on which the upper part of Temescal Creek is labeled ‘Temecula Cañon….’”
