6935-497: The stock of the Empire Consolidated Quicksilver Mining Company, which was bid in for $ 750 by William Hughes of 100 Nassau Street. The stock was seized ... to satisfy a judgement ... against Riley A. Boggess. The stock had been pledged with the North American Trust Company to secure loans. ... ” The Times reported April 21, 1903. The Sulphur Bank mercury mine next became the possession of George T. Ruddock,
7030-488: The stream means that it takes a very long time to drain excess flow from Clear Lake, increasing the chance of flooding around the lake. The bottleneck is seen as a backup to prevent flooding downstream and Yolo County is prohibited from increasing the capacity of the channel by the Gopcevic and Bemmerly Decrees. The Indian Valley dam on the North Fork of Cache Creek forms Indian Valley Reservoir . The dam's primary purpose
7125-520: The stream's water. Degradation of the channel caused by invasive plants , such as Arundo donax and Tamarix spp., as well as gravel mining has left no suitable habitat for Chinook salmon and steelhead to spawn , even if there is enough water. Consequently, there are no longer any anadromous fish species in Cache Creek. Cache Creek was added to California's Wild and Scenic Rivers System in October 2005 which protects 31 miles (50 km) of
7220-517: The up to 1,800 miners, are scattered about the park, with the biggest concentration at what was known as English Camp, established by Cornish miners in the 1860s. Some structures were built later by the U.S. Army Corps of Engineers and there is a memorial honoring the Civilian Conservation Corps firefighters who were stationed there for a time. Two California Historical Landmark markers honor New Almaden Mine: #339 marks
7315-460: The western United States usually includes the names of watchmen or mine personnel at the sites he studied, but no names are mentioned during his visits to Sulphur Bank. The Fiedler shaft was flooded and overflowing into Clear Lake in 1887. The mine was operated sporadically in the 1890s, evidenced by the presence of mine superintendent Richard White. John Parrott died in 1884, and his widow, Abigail inherited control of Parrott and Company. John Parrott
7410-410: Was a fraction of the output reported during the census of 1880 (10,706 flasks). The township of Eastlake, which included a dry goods store, post office and a hotel-restaurant was abandoned after the mine's closure. The mine was apparently inactive through the remainder of the 1880s. Geologist George F. Becker visited the mine several times between 1883 and 1888. Becker's survey of quicksilver mining in
7505-501: Was acquired by Tiburcio and John Parrott, William F. Babcock and Darius Ogden Mills , for the purpose of quicksilver mining at Sulphur Bank. Until 1875, when the mine shipped 5,218 flasks of mercury, it operated under the name of the borax company but then changed the name to the Sulphur Bank Quicksilver Mining Company. Tiburcio Parrott was controlling partner of the new company, and it was he who
7600-501: Was allowed to sell it to American investors for $ 1.75 million. Arthur De Wint Foote worked at New Almaden in the late 1870s under James Butterworth Randol . Representations of historical life at the New Almaden Mine were drawn in vivid detail by Mary Hallock Foote , the wife of Arthur DeWint Foote, the resident engineer from 1876. Her illustrated correspondence about New Almaden, "A California Mining Camp", appeared in
7695-464: Was an officer of Parrott and Company and was a partner with Tiburcio Parrott in an import-export company. Mills was also asset rich, founding the Bank of California, but who had stepped down as bank president by the time of the Sulphur Bank mercury mining era. It was Mills who later saved Bank of California with his personal assets when it failed under William Chapman Ralston . The period of 1875 to 1883
7790-428: Was employed a decade later when the Bradley Mining Company acquired the Sulphur Bank mercury mine. Frederick Worthen Bradley, the head and founder of the family-owned Bradley Mining Company, became both famous and infamous in 19th Century American history, unknowingly surviving two assassination attempts and setting records for low-cost ore production. His history is well documented on both the internet and print. There
7885-411: Was first worked for borax . Mining for sulfur began in 1865, and produced 2,000,000 pounds (909,090 kg) in four years. Mercury ore was mined intermittently by underground and open-pit methods from 1873 to 1957. Sulphur Bank Mine was credited with a total output of 92,400 flasks (7.02 million pounds) by 1918. The mine was an important producer during both world wars. The mine closed in 1957 and
7980-576: Was later jailed when the company refused to abide by a state law excluding Chinese from employment. Tiburcio's father, John Parrott, was a wealthy banker. Parrot and Company, of San Francisco was a major landholder and banking firm. John Parrot's weekend retreat consisted of 17,000 acres (69 km) in San Mateo County, California. John Parrot also owned 8% of the giant New Almaden quicksilver mine in Santa Clara County. Babcock
8075-463: Was later modified to include a 3 MW hydroelectric plant. The stream has a relatively small capacity, less than a quarter of the amount the dam is able to release. There is a rock ledge a mile and a half downstream of Clear Lake, called the Grigsby Riffle, near the bridge on State Route 53 . This ledge restricts the amount of water that can flow through at that point. The limited capacity of
8170-503: Was listed as owner/ general manager. “It is greatly to be regretted that the management of this property has not taken pains to preserve geological descriptions of the underground works, which are all caved in, except the Empire shaft, now in progress of sinking. The latter is so tightly timbered, owing to bad ground, that it offers no opportunity’ to study the formations through which it has passed,” wrote William Forstner, of California State Mining Bureau. He also observed that Sulphur Bank had
8265-761: Was made on behalf of the Quicksilver Mining Company, which had acquired a competing land claim originating in an agricultural claim to the land the mine was on. On appeal to the Supreme Court of the United States the claim was found invalid in a decision rendered March 10, 1863. One of the competing land claims was Rancho Los Capitancillos . The mine is named for a mercury mine in (old) Almadén , Spain , which had operated since at least Roman times. (See Heritage of Mercury. Almadén and Idrija .) The term Almadén, meaning "the mine",
8360-400: Was now headed by Riley Boggess’ wife, Emma, which still held possession of the Abbott and other mines near Sulphur Creek in Colusa and Lake counties. Neither the Abbott nor Sulphur Bank were being actively worked. “For the present at least, no underground work is planned, there being several hundred thousand tons at the surface, estimated as material available for treatment ... Practically all of
8455-468: Was situated in a grove of oaks on the north bank of Cache Creek one mile (1.6 km) east of the present town of Yolo, California . Cache Creek was originally known to the Hudson's Bay Company trappers as Rivière la Cache . Cache Creek was temporarily blocked north of Rumsey by a landslide caused by the 1906 San Francisco earthquake : Our Rumsey correspondent mentions the fall of Cache Creek as
8550-554: Was the American Consul to Mexico at Mazatlan . The War with Mexico in 1845-1846 put a temporary end to the diplomacy business. John Parrott then set up his banking and real estate business in San Francisco in 1848 or 1850. John Parrot's son by Deloris Ochoa., Tiburcio Parrott, was educated in the United States and Europe. After the failure of the mercury mine, he spent the last decade of his life founding and operating
8645-478: Was the furnace operator and postmaster at the New Almaden mine before taking the post of superintendent at Sulphur Bank. The mine's owner-investors all lived in San Francisco. Eastlake was directly adjacent to the mining property. After the mine closed, Eastlake was abandoned. Those who worked at the mine in 1880 constituted an ethnic soup of foreign-born workers. The 1880 federal census, dated June 22, 1880, listed 218 Chinese-born men and 40 Occidentals associated with
8740-457: Was the heyday of the mining activity. The Sulphur Bank Quicksilver Mine often had the highest output after the New Almaden, the New Idria (San Benito County) and the Redington. However, profits were tempered by the temperature of the underground workings. The Chinese miners, who did most of the underground work, had to endure temperatures of 176 °F (80 °C) because the ore body followed
8835-423: Was then a part). The Silverado rush in the winter of 1858–59 caused “every unemployed man from Soscol to Calistoga turned prospector. Blankets and bacon, beans and hard bread rose to a premium,” reported William T. Montgomery in a light-hearted sketch of the great silver rush that resulted in enormous finds of worthless iron pyrites . But the rush did result in the discovery of cinnabar in 1860. Montgomery, who became
8930-476: Was treated in furnaces and retorts near the mine. The essential refining method was to turn the mercury into gas and recondense it to quicksilver. The sulfur would burn and convert to sulfur dioxide; the waste rock associated with the ore is known as calcine, or burnt rock, would be dumped near the lake shore, out of the way of the mining works. All of the furnaces at all of the mines in the vicinity were wood fired. The heyday of quicksilver mining came to an end when
9025-473: Was widely popular in Cache Creek's upper watershed, given its gold recovering properties. At the peak of mercury production, over 6 million pounds (2.7 million kg) of mercury were mined, creating large mining caverns across the entirety of California. Throughout this period, little to no environmental regulations had been established causing mercury, in the form of mining waste from retorting , to infiltrate water systems and make its way into Cache Creek .
