St. John's Mine

Sulphur Springs Mountain (or Sulfur Springs Mountain) is a mountain in southwestern Solano County, California. The slopes can be accessed via hiking trails emanating from Blue Rock Springs Park in the city of Vallejo. Cinnabar deposits were extracted from this location in the early 1900s at Hastings Mine and St. John's Mine. Both mines are classified as medium priority mine from the standpoint of environmental oversight for California inactive mines. The highest peak on Sulfur Springs Mountain stands at an elevation of 1,112 feet (339 m), and affords expansive views of the northern San Francisco Bay as well as the Napa River. The rock outcroppings which occur in the Sulphur Springs area are composed of basaltic lava; however, there are also serpentine outcrops, which soils are known to provide habitat for many rare and endangered species in Northern California.

The Hastings Mine is a mineral extraction site approximately 4.5 miles (7.2 km) northeast of the city of Vallejo, Solano County, California. The Hastings site on Sulfur Springs Mountain was used for extraction of cinnabar until the year 1930. The Hastings Mine is classified as a medium priority mine from the standpoint of environmental oversight. In the last inspection of the Hastings Mine in 1997, sediments in a drainage below the mine were found to contain ten parts per million of mercury; furthermore, spring water below the mine exhibited a water concentration of .31 micrograms per liter (a violation of the State of California standard for receiving waters of .05 micrograms per liter). Miles of underground shafts were driven in the course of working the quicksilver deposits in the area. In 1989, Earth Metrics reviewed old 1918 maps of workings of the Hastings and St. John's Mines and found that mine shafts were not driven into the site prior to the year 1918.

Blue Rock Springs Creek is a 3.4-mile-long (5.5 km) stream that rises on Sulfur Springs Mountain in southwestern Solano County, California. A bicycle trail is positioned along the creekside in some of the lower reaches. Water quality is impaired in Blue Rock Springs Creek due to historic cinnabar extraction in this watershed. Blue Rock Springs Creek has been tested for the toxin diazinon and found to have attained an elevated value of 40.9 micrograms per liter; diazinon is a toxic pesticide associated with golf course maintenance. The 36-hole Blue Rock Springs Golf Course lies in this watershed; although diazinon has been banned for golf course use in the U.S., its persistence in the environment is quite high. The stream has had application of a hydrological transport model to analyze flooding potential and to aid in the design of certain stream channel modification carried out in the last quarter of the 20th century to accommodate urbanization of some of the lower reaches. Cinnabar deposits were extracted from this watershed in the early 1900s at Hastings Mine and St. John's Mine. Shaft construction occurred no earlier than 1918 and mining had ceased by the year 1930.
