USGS Open-File Report 99-18B is a digital representation
of a paper map that is being released simultaneously, USGS
Open-File Report 99-18A. The map shows the bedrock
geology of the Seldovia quadrangle, Alaska, at a scale of
1:250,000, compiled from new mapping (1988-1993) and
published sources. Digital files include various map
coverages in Arc/Info export format, and a picture of the
map plus all map-collar information in Adobe Illustrator
and PDF formats. The map collar includes detailed
map-unit descriptions, text on the physiography,
neotectonics, geologic history, and economic geology,
cross-section, correlation of map units chart, and map
showing original sources of information.
Digital representation of geologic mapping of the Seldovia
quadrangle, Alaska, is to facilitate the presentation and
analysis of earth-science data. Digital maps can be
displayed at any scale or projection, however the
geological data in this coverage is not intended for use
at a scale larger that 1:250,000.
The 1:63,360 scale geologic maps (ink or mylar topographic
bases), from which the present map was compiled, are
housed at the U.S. Geological Survey, 4200 University
Drive, Anchorage, Alaska 99508. These show more detail
than the present map, which was simplified, in places, for
display at 1:250,000 scale.
