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. Metadata

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.

Four film positives of topography [which was prepared in 1943 and subsequently used by Page and Nokleberg (1974) for a base map for the geology of the Stillwater Complex, Montana] were scanned, and the resulting TIFF images were then geoferenced, rectified, and spliced together to create i797base.tif.

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.

The Floodplain Mapping/Redelineation study deliverables depict and quantify the flood risks for the study area. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual- chance flood event, and areas of minimal flood risk. The Floodplain Mapping/Redelineation flood risk boundaries are derived from the engineering information Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA).

The SSURGO database contains information about soil as collected by the National Cooperative Soil Survey over the course of a century. The information was gathered by walking over the land and observing the soil. Many soil samples were analyzed in laboratories.

The maps outline areas called map units. The map units describe soils and other components that have unique properties, interpretations, and productivity. The information was collected at scales ranging from 1:12,000 to 1:63,360.

The mapping is intended for natural resource planning and management by landowners, townships, and counties. Some knowledge of soils data and map scale is necessary to avoid misunderstandings.

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 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.
