Map showing flood-prone areas, greater Denver area, Front Range Urban Corridor, Colorado
The rapid growth of population in the Front Range Urban Corridor of Colorado is causing intense competition for available land resources. One form of competition posing serious problems in indiscriminate development on flood plains along creeks and rivers. Flood plains are natural features of the landscape developed by streams in carry water in excess of channel capacity. Although not used as ofte
Map showing fluorspar deposits in Colorado
Increased fluorine consumption (U.S. Bureau of Mines, 1946-1971) coupled with limited proved reserves has stimulated extensive exploration for fluorine and intensive research into developing new sources of fluorine or substitutes. A summary of the distribution, geochemical and geologic environments, and production history of selected fluorspar occurrences, deposits, and districts is provided here
Map showing foundation conditions in the Fairbanks D-1 SW Quadrangle, Alaska
In the Fairbanks area, the effects of development on the geologic environment must be considered in determining proper land use. Persons concerned with the land, especially land planners, developers, public officials, engineers, architects, financial advisors, and educators, must be aware of recognizable geologic features that may prove hazardous; only then can proper and economical land usage be
Map showing foundation conditions in the Fairbanks D-2 NE Quadrangle, Alaska
In the Fairbanks area, the effects of development on the geologic environment must be considered in determining proper land use. Persons concerned with the land, especially land planners, developers, public officials, engineers, architects, financial advisors, and educators, must be aware of recognizable geologic features that may prove hazardous; only then can proper and economical land usage be
Map showing foundation conditions in the Fairbanks D-2 NW Quadrangle, Alaska
In the Fairbanks area, the effects of development on the geologic environment must be considered in determining proper land use. Persons concerned with the land, especially land planners, developers, public officials, engineers, architects, financial advisors, and educators, must be aware of recognizable geologic features that may prove hazardous; only then can proper and economical land usage be
Map showing foundation conditions in the Fairbanks D-2 SE Quadrangle, Alaska
In the Fairbanks area, the effects of development on the geologic environment must be considered in determining proper land use. Persons concerned with the land, especially land planners, developers, public officials, engineers, architects, financial advisors, and educators, must be aware of recognizable geologic features that may prove hazardous; only then can proper and economical land usage be
Map showing ground water conditions in the Fairbanks D-1 SW quadrangle, Alaska
The primary controlling factors determining ground-water conditions in the Fairbanks D-1 SW quadrangle are (1) topographic position, (2) water-bearing characteristics of the rocks, and (3) distribution of permafrost. These interrelated factors generally limit the conditions in any particular area. Basic data from the geologic map of the Fairbanks D-1 SW quadrangle (Map I-949, Pewe and others, in p
