Database of Montana Counties created to be coincident with the Montana Cadastral Parcel Boundaries. Where county boundaries are coincident with public land survey section lines, they were copied from the BLM's Geographic Coordinate Database (GCDB). If boundaries were not coincident with GCDB lines, they were digitized on screen from 1:24,000 scale Geological Survey Digital Raster Graphics (DRGs). County Boundaries will change as the GCDB is adjusted by the BLM and those data are imported into the Cadastral Data Model.

The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. County subdivisions are the primary divisions of counties and their equivalent entities for the reporting of Census Bureau data. They include legally- recognized minor civil divisions (MCDs) and statistical census county divisions (CCDs), and unorganized territories. For the 2010 Census, the MCDs are the primary governmental and/or administrative divisions of counties in 29 States and Puerto Rico; Tennessee changed from having CCDs for Census 2000 to having MCDs for the 2010 Census. In MCD States where no MCD exists or is not defined, the Census Bureau creates statistical unorganized territories to complete coverage. The entire area of the United States, Puerto Rico, and the Island Areas are covered by county subdivisions. The boundaries of most legal MCDs are as of January 1, 2018, as reported through the Census Bureau's Boundary and Annexation Survey (BAS). The boundaries of all CCDs, delineated in 20 states, are those as reported as part of the Census Bureau's Participant Statistical Areas Program (PSAP) for the 2010 Census.

The Strawberry Butte quadrangle, scale 1:24,000, is a legacy map of the U.S. Geological Survey, made as part of the Montana Investigations Project to provide information on the stratigraphy, structure, and geologic history of the area. The quadrangle encompasses an area of about 132 km2 (51 mi2) in the southwest part of the Little Belt Mountains and is about 26 km (17 mi) north of White Sulphur Springs, county seat of Meagher County, Montana. Two contrasting geologic terranes form the area. The northern two-thirds of the quadrangle are underlain by Paleoproterozoic metagranite that contains some inclusions of metadiorite and biotite gneiss. A veneer of Middle Cambrian sedimentary rocks, including the Flathead Sandstone at the base and overlying Wolsey Formation, Meagher Limestone, and Park Shale, is exposed discontinuously across the Paleoproterozoic metamorphic rocks. The southern third of the quadrangle, separated from the metamorphic rocks by the Volcano Valley fault zone, is underlain by Mesoproterozoic strata of the Newland Formation which are deformed in anticlines and synclines generally parallel to the fault zone. Eocene dacite sills and dikes intrude the Newland Formation south of the fault, and Eocene monzonite and dacite are locally present high in the northeast corner of the area. Oligocene andesitic basalt and tuffaceous sedimentary rocks of Oligocene and Miocene age are present in a northwest-trending paleo valley of probable late Eocene age in the northwestern third of the quadrangle and in the southeast corner of the quadrangle. The Volcano Valley fault zone is a complex zone of dominantly high-angle faulting, active during several intervals of geologic time. Prior to deposition of the Flathead Sandstone, the area on north side of the fault zone moved up, so that erosion removed Mesoproterozoic rocks on that side to expose Paleoproterozoic rocks before deposition of the Middle Cambrian strata. Movement along the zone recurred in early Eocene time as the south block moved up and east. Subsequently likely in late Eocene time, the block north of the Volcano Butte fault zone arched upward as normal faults north of that fault accommodated movement along the margin of the arch. A parallel fault zone, the Black Butte Creek fault zone, diverges from, and extends parallel to the Volcano Valley fault zone across the southern part of the quadrangle. The Black Butte Creek fault zone displays both left lateral strike slip movement and normal movement up on the south side. The two major fault zones together form a segment of the northern margin of the Helena structural salient in west-central Montana. Alluvium and terrace gravel of Holocene and Pleistocene age are present along the northwest courses of both Black Butte Creek and Sheep Creek and the southeast course of Newland Creek. Boulder deposits, derived from areas as far as 10-12 km to the east, are present in the southwest part of the area. Debris from excavations in iron gossan mantles slopes on the south block of the Volcano Valley fault zone. The debris and mapped iron-stained bedrock of the Newland Formation have drawn attention to the potential occurrence of economic sulfide mineralization in the area. Subsequent to mapping the quadrangle, an exploration company has identified in the subsurface a limited area of copper- and cobalt-enriched rock in the Newland Formation in the southeast part of the quadrangle and has proposed to mine the deposit. The current geologic quadrangle map defines a surface geologic baseline from which exploration and resource agencies alike can potentially evaluate the areal distribution of possible mineralization as well as the environmental effects of development of a proposed mine.

This Data Release contains geospatially-enabled geological data to accompany the Geologic Map of the Central Beaverhead Mountains, Lemhi County, Idaho, and Beaverhead County, Montana. This map portrays detailed geology of the central Beaverhead Mountains, printable at 1:50,000 scale. These data were collected between 1997 and 2017, and synthesized to provide significant new stratigraphic and structural data and interpretations. Generalized basin geology compiled from sources on both sides of the range is combined with newly mapped bedrock geology to better integrate geologic development of the map area.

Montana Boundaries Map Service includes the following boundaries: State, County, Incorporated City/Town, Reservation, School Districts, and Tax Increment Financing Districts. These boundaries were collected using a federated approach and using the best source documentation available. Please contact the Administrative Boundaries Coordinator for more information about this data or view individual data layer metadata documents Metadata for the web service.

Feature class of Montana State Boundary was created to be coincident with the Montana County Boundaries, GCDB, and Cadastral Parcel Boundaries. Where the boundary is coincident with public land survey section lines, they were copied from the BLM's Geographic Coordinate Database (GCDB). If boundary was not coincident with GCDB lines, they were digitized on screen from 1:24,000 scale Geological Survey Digital Raster Graphics (DRGs). The state boundary will change as the GCDB / Montana CadNSDI is adjusted by the BLM / Montana State Library and those data are incorporated with the Montana Spatial Data Infrastructure Administrative Boundaries & Cadastral datasets.

The geologic and structure map of Choteau 1 x 2 degree quadrangle (Mudge and others, 1982) was originally converted to a digital format by Jeff Silkwood (U.S. Forest Service and completed by the U.S. Geological Survey staff and contractor at the Spokane Field Office (WA) in 2000 for input into a geographic information system (GIS). The resulting digital geologic map (GIS) database can be queried in many ways to produce a variey of geologic maps. Digital base map data files (topography, roads, towns, rivers and lakes, etc.) are not included: they may be obtained from a variety of commercial and government sources. This database is not meant to be used or displayed at any scale larger than 1:250,000 (e.g. 1:100,000 or 1:24,000. The digital geologic map graphics and plot files (chot250k.gra/.hp/.eps and chot-map.pdf) that are provided in the digital package are representations of the digital database. They are not designed to be cartographic products.

The data release for the geologic map of the Butte 1 degree x 2 degrees quadrangle, Montana, is a Geologic Map Schema (GeMS)-compliant version that updates the GIS files for the geologic map published in Montana Bureau of Mines and Geology Open File Report MBMG 363 (Lewis, 1998). The updated digital data present the attribute tables and geospatial features (points, lines and polygons) in the format that meets GeMS requirements. This data release presents the geologic map as shown on the plates and captured in geospatial data for the published map. Minor errors, such as mistakes in line decoration or differences between the digital data and the map image, are corrected in this version.

The map covers parts of Deer Lodge, Granite, Jefferson, Lewis and Clark, Missoula, Powell, Ravalli, and Silver Bow Counties. These GIS data supersede ...

The 2015 cartographic boundary shapefiles are simplified representations of selected geographic areas from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). These boundary files are specifically designed for small-scale thematic mapping. When possible, generalization is performed with the intent to maintain the hierarchical relationships among geographies and to maintain the alignment of geographies within a file set for a given year. Geographic areas may not align with the same areas from another year. Some geographies are available as nation-based files while others are available only as state-based files. The records in this file allow users to map the parts of Urban Areas that overlap a particular county. After each decennial census, the Census Bureau delineates urban areas that represent densely developed territory, encompassing residential, commercial, and other nonresidential urban land uses. In general, this territory consists of areas of high population density and urban land use resulting in a representation of the "urban footprint." There are two types of urban areas: urbanized areas (UAs) that contain 50,000 or more people and urban clusters (UCs) that contain at least 2,500 people, but fewer than 50,000 people (except in the U.S. Virgin Islands and Guam which each contain urban clusters with populations greater than 50,000). Each urban area is identified by a 5-character numeric census code that may contain leading zeroes. The primary legal divisions of most states are termed counties. In Louisiana, these divisions are known as parishes. In Alaska, which has no counties, the equivalent entities are the organized boroughs, city and boroughs, municipalities, and for the unorganized area, census areas. The latter are delineated cooperatively for statistical purposes by the State of Alaska and the Census Bureau. In four states (Maryland, Missouri, Nevada, and Virginia), there are one or more incorporated places that are independent of any county organization and thus constitute primary divisions of their states. These incorporated places are known as independent cities and are treated as equivalent entities for purposes of data presentation. The District of Columbia and Guam have no primary divisions, and each area is considered an equivalent entity for purposes of data presentation. The Census Bureau treats the following entities as equivalents of counties for purposes of data presentation: Municipios in Puerto Rico, Districts and Islands in American Samoa, Municipalities in the Commonwealth of the Northern Mariana Islands, and Islands in the U.S. Virgin Islands. The entire area of the United States, Puerto Rico, and the Island Areas is covered by counties or equivalent entities. The boundaries for counties and equivalent entities are as of January 1, 2010.

The Ennis 1:100,000 quadrangle lies within both the Laramide (Late Cretaceous to early Tertiary) foreland province of southwestern Montana and the northeastern margin of the middle to late Tertiary Basin and Range province.

The oldest rocks in the quadrangle are Archean high-grade gneiss, and granitic to ultramafic intrusive rocks that are as old as about 3.0 Ga. The gneiss includes a supracrustal assemblage of quartz-feldspar gneiss, amphibolite, quartzite, and biotite schist and gneiss. The basement rocks are overlain by a platform sequence of sedimentary rocks as old as Cambrian Flathead Quartzite and as young as Upper Cretaceous Livingston Group sandstones, shales, and volcanic rocks.

The Archean crystalline rocks crop out in the cores of large basement uplifts, most notably the "Madison-Gravelly arch" that includes parts of the present Tobacco Root Mountains and the Gravelly, Madison, and Gallatin Ranges. These basement uplifts or blocks were thrust westward during the Laramide orogeny over rocks as young as Upper Cretaceous. The thrusts are now exposed in the quadrangle along the western flanks of the Gravelly and Madison Ranges (the Greenhorn thrust and the Hilgard fault system, respectively). Simultaneous with the west-directed thrusting, northwest-striking, northeast-side-up reverse faults formed a parallel set across southwestern Montana; the largest of these is the Spanish Peaks fault, which cuts prominently across the Ennis quadrangle.

Beginning in late Eocene time, extensive volcanism of the Absorka Volcanic Supergroup covered large parts of the area; large remnants of the volcanic field remain in the eastern part of the quadrangle. The volcanism was concurrent with, and followed by, middle Tertiary extension. During this time, the axial zone of the "Madison-Gravelly arch," a large Laramide uplift, collapsed, forming the Madison Valley, structurally a complex down-to-the-east half graben. Basin deposits as thick as 4,500 m filled the graben.

Pleistocene glaciers sculpted the high peaks of the mountain ranges and formed the present rugged topography.

Compilation scale is 1:100,000. Geology mapped between 1988 and 1995. Compilation completed 1997. Review and revision completed 1997. Archive files prepared 1998-02.

This quadrangle lies 6.4 km (4 mi) northeast of Bozeman, Mont., in southwestern Montana. Metamorphic, sedimentary, and volcanic rocks of Precambrian to Tertiary age are exposed in the Bridger Range and southwestern margin of the Crazy Mountains Basin in a crustal cross section and a structural triangle zone. Surface geology records Precambrian extension, Late Paleocene east-vergent contraction, including backthrusts, and Holocene basin-range extension.

The data release for the geologic map of the Dillon 1 x 2 degrees quadrangle, Idaho and Montana, is a Geologic Map Schema (GeMS)-compliant version that updates the GIS files for the geologic map published in U.S. Geological Survey (USGS) Miscellaneous Investigations Series Map I-1803-H (Ruppel and others, 1993).

The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Census tracts are small, relatively permanent statistical subdivisions of a county or equivalent entity, and were defined by local participants as part of the 2020 Census Participant Statistical Areas Program. The Census Bureau delineated the census tracts in situations where no local participant existed or where all the potential participants declined to participate. The primary purpose of census tracts is to provide a stable set of geographic units for the presentation of census data and comparison back to previous decennial censuses. Census tracts generally have a population size between 1,200 and 8,000 people, with an optimum size of 4,000 people. When first delineated, census tracts were designed to be homogeneous with respect to population characteristics, economic status, and living conditions. The spatial size of census tracts varies widely depending on the density of settlement. Physical changes in street patterns caused by highway construction, new development, and so forth, may require boundary revisions. In addition, census tracts occasionally are split due to population growth, or combined as a result of substantial population decline. Census tract boundaries generally follow visible and identifiable features. They may follow legal boundaries such as minor civil division (MCD) or incorporated place boundaries in some States and situations to allow for census tract-to-governmental unit relationships where the governmental boundaries tend to remain unchanged between censuses. State and county boundaries always are census tract boundaries in the standard census geographic hierarchy. In a few rare instances, a census tract may consist of noncontiguous areas. These noncontiguous areas may occur where the census tracts are coextensive with all or parts of legal entities that are themselves noncontiguous. For the 2010 Census and beyond, the census tract code range of 9400 through 9499 was enforced for census tracts that include a majority American Indian population according to Census 2000 data and/or their area was primarily covered by federally recognized American Indian reservations and/or off-reservation trust lands; the code range 9800 through 9899 was enforced for those census tracts that contained little or no population and represented a relatively large special land use area such as a National Park, military installation, or a business/industrial park; and the code range 9900 through 9998 was enforced for those census tracts that contained only water area, no land area.

Gallatin County, MT has a B wealth grade. Median household income: $89,484. Unemployment rate: 2.3%. Income grows 6.7% yearly.

The digital geologic map of the east slope of Iron Mountain, Sweet Grass County, Montana was prepared from preliminary digital datasets digitized by Optronics Specialty Co., Inc. from a paper copy of plate 10 from UGSG Bulletin 1015-D (Howland, 1955).The files were prepared and transformed to the Montana State Plane South projection by Helen Z. Kayser (Information Systems Support, Inc.). Further editing and attributing was performed by Lorre A. Moyer in 2001. The resulting spatial digital database can be queried in many ways to produce a variety of derivative geologic maps.

The geology of western and northern Gallatin National Forest was mapped in two parts as part of an evaluation of its mineral resource potential by the USGS. Previously, the western part was released as Map A and the northern part as Map B of USGS Geologic Investigations Series Map I-2584. These maps were compiled, digitized, and produced using the USGS software program GSMAP. All the original source maps were simplified on mylar overlays, digitized at their original map scales and projections, and then merged into the final maps. After editing, the digital maps were filtered to remove all points not necessary for improving resolution at a scale of 1:126,720 (2 mi per in., the scale used by the USDA Forest Service). For purposes of resource assessment, many rock units have been combined on these maps. For details, the user should consult the original source maps.

The Sewer Districts are mapped from various geographies. They have been projected to Montana State Plane NAD83(2011) meters [wkid: 6514].

Madison County, MT has a C wealth grade. Median household income: $67,113. Unemployment rate: 1.5%. Income grows 5.3% yearly.
