Description: This dataset provides historical coal mine maps and locations. Each point represents the relative location of a known mine. All inventoried maps for a given mine are connected to the respective location point of that mine. For the full inventory list see the "Coal Mine Maps Inventory" table.

Description: Biekman and others (1984) and Valentine and Huntting (1960) published information about known coal fields in Washington State, where coal reserves and resources have been identified and characterized. This layer shows coal reserves. Reserves are that part of a resource that is economically mineable.
Description: Biekman and others (1984) and Valentine and Huntting (1960) published information about known coal fields in Washington State, where coal reserves and resources have been identified and characterized. Coal fields are larger areas within which numerous coal deposits are found, whereas coal locations are isolated locations and coal reserves are those areas that are mineable.
Description: IAML PointsOver 3,800 mineral properties have been located in the state during the last 150 years (Huntting, 1956). Many are undeveloped prospects of little economic importance. Sites that meet one of the following criteria are included: (a) more than 2000 feet of underground development, (b) more than 10,000 tons of production, (c) location of a known mill site or smelter. This subset of sites includes only metal mines no longer in operation. The term inactive, in addition to the term abandoned is used because it more precisely describes the land-use situation regarding mining and avoids any political or legal implications of surrendering an interest to a property that may re-open with changes in economics, technology, or commodity importance. This point data layer provides information about each site as a whole. Some sites (the Eureka Gulch area, the Monte Cristo district, the Pend Oreille west side workings, and the Roy and Barnum McDonnell mines) are lumped into single records. The names by which the mines at each of these sites are commonly known are included as separate records.IAML FeaturesIAML features include (a) mine developments (adits, shafts, stopes, pits, etc.); (b) details on waste rock and tailings dumps; (c) mine drainage and impounded water; and (d) brief details on mine related structures.

Description: Nonmetallic Mineral LocationsGeologists use the term 'Industrial Minerals' to describe nonmetallic minerals that have economic or industrial uses. Their characteristics and means of formation are highly variable. Examples of these minerals include garnet, fluorite, quartz, beryl, sulfur, gypsum, mica, and many others.Metallic Mineral LocationsMetallic minerals are elements or compounds that are generally hard, shiny, malleable, and usually have good electrical and thermal conductivity and high density. Examples of these minerals include antimony, chromium, copper, silver, gold, iron, and manganese. These characteristics make them desirable for use in most of the products we use every day. We have electronically compiled thousands of documents, maps, and data from multiple sources to provide access to metallic mineral data in Washington State.

Description: Mercury, called quicksilver by miners, is silver to white, and the only metal which is liquid at room temperature. It is typically extracted from the mineral cinnabar by heating the crushed ore. Mercury is highly toxic and can be absorbed through the skin or inhaled as mercury vapor. Mercury may also enter the food chain and become a health hazard to animals and humans. The Washington Geological Survey has compiled data pertaining to historic prospects and (or) mines within Washington known to have produced mercury as a primary commodity or as a byproduct of mining.
Description: Asbestos is the general term for a number of minerals belonging to the serpentine and amphibole groups that have similar properties. Asbestiform minerals are composed of very thin, long fibrous crystals, and it is this fibrous nature that makes them dangerous. Asbestos is frequently associated with serpentinite and partially serpentinized ultramafic/ultrabasic rocks (however, not all ultrabasic rocks are serpentinite bearing). The Washington Geological Survey has compiled data pertaining to historic prospects and (or) mines within Washington known to have produced asbestos as a primary commodity or as a byproduct of mining.
Description: Arsenic is found in many rocks and minerals and is generally associated with sulfur. The most common arsenic minerals are arsenopyrite, and the sulfides, realgar and orpiment. These minerals can cause respiratory problems when inhaled, particularly at mine sites that are popular for motorized recreational vehicle use. Additionally, water discharged from metal mine openings may contain these same minerals in solution and present a health hazard to humans and animals. Arsenic is especially dangerous when it contaminates groundwater and poisons drinking water.The Washington Geological Survey has compiled data pertaining to historic prospects and (or) mines within Washington known to have produced arsenic as a primary commodity or as a byproduct of mining.

WGS has compiled data pertaining to historic prospects and (or) mines within Washington known to have produced asbestos as a primary commodity or as a byproduct of mining. This layer differs from Asbestos Locations in that it displays rock units that potentially contain asbestos, compiled from 1:100,000-scale geologic maps, rather than specific locations known to have produced asbestos as a primary commodity or mined a mineral type that can potentially produce asbestos.
Description: Radon is produced by natural radioactive decay of uranium (and (or) thorium) and is particularly associated with uraniferous two-mica granites. Radon is carcinogenic and a prominent cause of lung cancer. Radon is colorless, odorless, and tasteless, making it exceptionally hazardous, as its presence is revealed only by specific detectors. This layer contains the locations of historic metallic mines within the State of Washington known to have produced uranium as a primary commodity or as a by-product of the mining.
Description: The Washington Geological Survey has compiled data from 1:100,000-scale geologic mapping and a uranium-bearing mineral geology dataset produced by Goetz (1993) to produce a classified dataset showing radon hazard. In this dataset the potential for uranium in the rocks and soils is classified as high, moderately high, moderate, variable, or low.
Description: This dataset contains outlines of the mining districts of Washington State derived from unpublished paper maps within the Survey's collection
