  • Korbel (east of), Humboldt County, California – Three Creeks Prospect (Limestone) (Excerpt from "Limestone in California," by Clarence A. Logan, California Journal of Mines and Geology, Vol. 43, No. 3, July 1947, California Division of Mines, San Francisco, California, pp. 175-357. Used with permission, California Department of Conservation, California Geological Survey.)

    "Three Creeks prospect is in sec. 33, T. 7 N., R. 4 E., over 20 miles east of Korbel, the nearest railroad point. The prospect consisted of boulders of limestone, some several tons in weight, strewn over areas totalling (sic) a few acres (Averill, C. V. 41, p. 517).* No development had been done. This limestone has been classed as Devonian by Harry McGinitie, Humboldt State College."

  • Petrolia (8 miles from), Humboldt County, California - Johnston Limestone Deposit (Limestone) (Excerpt from "Limestone in California," by Clarence A. Logan, California Journal of Mines and Geology, Vol. 43, No. 3, July 1947, California Division of Mines, San Francisco, California, pp. 175-357.

    "Johnston deposit is in secs. 4 and 9, T. 2 S., R. 1 W., H., 8 miles by steep road from Petrolia and over 30 miles from the railroad. Small outcrops, the largest reported to contain 20 to 25 tons, occur at intervals for 2 miles in a northwesterly direction. They are probably part of the Franciscan formation."

  • Rio Del (southwest of), Humboldt County, California - Hackett Limestone Deposit (Limestone) (Excerpt from "Limestone in California," by Clarence A. Logan, California Journal of Mines and Geology, Vol. 43, No. 3, July 1947, California Division of Mines, San Francisco, California, pp. 175-357. Used with permission, California Department of Conservation, California Geological Survey.)

    "Hackett deposit is in sec. 10 or 16, T. 1 N., R. 1 W., 4 miles southwest of Rio Dell on the west Fork of Howe Creek in steep country 2 miles from a road. An outcrop 20 feet wide by 30 feet high is exposed on the bank of the creek, and some large boulders were seen, but no work had been done, so the amount of limestone concealed by the soil covering is unknown. No analysis is available. This deposit is about 5 miles from the railroad."

  • Rio Dell (2 miles from), Humboldt County, California - Rickter Limestone Deposit (Limestone) (Excerpt from "Limestone in California," by Clarence A. Logan, California Journal of Mines and Geology, Vol. 43, No. 3, July 1947, California Division of Mines, San Francisco, California, pp. 175-357. Used with permission, California Department of Conservation, California Geological Survey.)

    "Rickter deposit is in the SE SE sec. 11, T. 1 N., R. 1 W., 2 miles by road from Rio Dell, and about 3 miles from the Northwestern Pacific Railway. It has been quarried for agricultural use. According to a report by Charles V. Averill (41, p. 517) the quarry was 75 feet long, but the maximum depth reached in the limestone was only 25 feet. He stated the deposit might have a total length of 1000 feet, but stripping of overburden would be required to prove this. Backs of 100 feet could be had from the old quarry floor if the limestone extends that deep ahead of the present face, as the ridge rises beyond the quarry.

    "The deposit is soft limestone close to a fault contact between the Franciscan (?) and Pliocene marine sediments."

    • Trinidad, Humboldt County, California - Trinidad Quarry (Stone) (active ca 1996) (From Mines and Mineral Producers Active in California (1994-1995), Special Publication 103 (Revised 1996), California Department of Conservation, Division of Mines and Geology, in cooperation with California Department of Conservation, Office of Mine Reclamation. Used with permission, California Department of Conservation, California Geological Survey.)

      Mine name: Trinidad Quarry; Operator: Mercer, Fraser Company; Address & County: P.O. Box 1006, Eureka, CA 95502-1006, Humboldt County; Phone: (707) 443-6371; Latitude: 41.07, Longitude: -124.12, and Mine location number: Map No. 127; Mineral commodity: Stone.

  • Weymouth Inn (southwest of), Humboldt County, California - McClellan Calcareous Tufa Deposit (Calcareous Tufa/Limestone) (Excerpt from "Limestone in California," by Clarence A. Logan, California Journal of Mines and Geology, Vol. 43, No. 3, July 1947, California Division of Mines, San Francisco, California, pp. 175-357. Used with permission, California Department of Conservation, California Geological Survey.)

    "McClellan deposit is in sec. 5, T. 1 N., R. 1 W., H. 5 miles southwest of Weymouth Inn by steep road. It is a deposit of calcareous tufa, covering an area of an acre to a depth of 3 feet, according to Chas. V. Averill. Mr. E. S. McClellan, who owned and farmed the land in 1941, had used some of the limestone on the land and claimed an analysis indicated the tufa contains 99 percent CaCO3."

  • Willow Creek (south of), Humboldt County, California - White Rock Limestone Deposit (Limestone) (Excerpt from "Limestone in California," by Clarence A. Logan, California Journal of Mines and Geology, Vol. 43, No. 3, July 1947, California Division of Mines, San Francisco, California, pp. 175-357. Used with permission, California Department of Conservation, California Geological Survey.)

    "White Rock deposit is in secs. 18, 19, T. 6 N., R. 5 E., about 5 miles south of Willow Creek P. O. near the eastern side of the county. Willow Creek, on state road 299, is 33 miles east of Korbel. This is apparently the largest deposit of limestone so far described in the county, being part of a series of limestone lenses which outcrop at intervals for a distance of many miles, striking north-northwest about parallel to the South Fork of Trinity River. This limestone was formerly listed as Devonian but the age may be in doubt as the deposit is near the indefinite western border of an area shown on the current state geologic map (Jenkins, O. P.38) as pre-Cambrian, and on an earlier state map (Smith, J. P. 16) of Paleozoic metamorphics, undifferentiated.

    "The deposit forms the top of a ridge and is reported to outcrop for a length of 800 feet over a width of 145 feet, and stands 50 feet high. It lies well for quarrying.

    "The following analysis was made for Alexander Brizard, Arcata (who claimed the land in 1940), by Smith Emery & Company (Averill, C. V. 41, p. 518):*

    (* Charles Volney Averill, "Mineral Resources of Humboldt County," California Division Mines Report 37, pp. 499-528, 1941.)

    SiO2, 0.34 percent
    Al2O3, 0.16 percent
    Fe2O3, 0.13 percent
    MgO, 0.53 percent
    CaO, 54.88 percent
    Purity as CaCO3, 97.95 percent
