This digital map shows bedding attitude data displayed over the geographic extent of rock stratigraphic units (formations) as compiled by Colton in 1976 (U.S.Geological Survey Map I-855-G) under the Front Range Urban Corridor Geology Program. Colton used his own mapping and published geologic maps having varied map unit schemes to compile one map with a uniform classification of geologic units. The resulting published color paper map was intended for planning for use of land in the Front Range Urban Corridor. In 1997-1999, under the USGS Front Range Infrastructure Resources Project, Colton's map was digitized to provide data at 1:100,000 scale to address urban growth issues(see cross-reference). In general, the...

50 year Projected Urban Growth scenarios. Base year is 2000. Projected year in this dataset is 2020. Acquired from Cal-Atlas at http://www.atlas.ca.gov/download.html#/casil/society.

These data represent the extent of urbanization (for the year indicated) predicted by the model SLEUTH, developed by Dr. Keith C. Clarke, at the University of California, Santa Barbara, Department of Geography and modified by David I. Donato of the United States Geological Survey (USGS) Eastern Geographic Science Center (EGSC). Further model modification and implementation was performed at the Biodiversity and Spatial Information Center at North Carolina State University. More information about these data (along with downloadable ESRI GRID files) can be found at http://www.basic.ncsu.edu/dsl/urb.html

By 2020, most forecasters agree, California will be home to between 43 and 46 million residents-up from 35 million today. Beyond 2020 the size of California's population is less certain. Depending on the composition of the population, and future fertility and migration rates, California's 2050 population could be as little as 50 million or as much as 70 million. One hundred years from now, if present trends continue, California could conceivably have as many as 90 million residents. Where these future residents will live and work is unclear. For most of the 20th Century, two-thirds of Californians have lived south of the Tehachapi Mountains and west of the San Jacinto Mountains-in that part of the state commonly...

This digital map shows bedding attitude symbols display overthe geographic extent of surficial deposits and rockstratigraphic units (formations) as compiled by Trimble andMachette 1973-1977 and published in 1979 (U.S. GeologicalSurvey Map I-856-H) under the Front Range Urban CorridorGeology Program. Trimble and Machette compiled their geologicmap from published geologic maps and unpublished geologicmapping having varied map unit schemes. A convenient feature ofthe compiled map is its uniform classification of geologicunits that mostly matches those of companion maps to thenorth (USGS I-855-G) and to the south (USGS I-857-F).Published as a color paper map, the Trimble and Machette mapwas intended for land-use planning...
