Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted.  For more information, please see www.doi.gov/shutdown

Iron Mountain, California: An Extraordinary and Extreme Environment

At its peak production, Iron Mountain ranked as the tenth largest copper production site in the world, sixth in the U.S. and first in California. During its operation, from 1879 - 1963, ten different mines throughout the site's 4,400 acres were the source of not just copper, but also silver, iron, gold, zinc and pyrite (iron sulfide).

Mercury is a rare, dense metal, slightly more common than gold in the earth's crust. Mercury occurs in several different forms, the most important of which is methylmercury. Methylmercury is the form most readily incorporated into biological tissues and most toxic to humans. Methylmercury accumulates and biomagnifies in the food chain, reaching highest concentrations in predatory fish such as...
