USGS Earth Science Information Center (ESIC)

Denver Federal Center, Lakewood, Colorado

You can purchase US Geological Survey maps and publications at the Earth Science Information Center (ESIC) on the grounds of the Denver Federal Center.  Don't be put off by the security guards at the gates.  The public is welcome to enter during working hours on work days through either Gate 4 on Union Street or Gate 1 on Kipling Street.  Just stop and tell the security guard that you are going to visit the Earth Science Information Center, also known as "map sales."

Below are some maps showing the location of the ESIC in the southwest corner of the Denver Federal Center.

The ESIC also has a public display area featuring kiosks with information on each of the USGS programs, a computer display of historic and recent seismicity, two interactive shake tables demonstrating two earthquake hazards issues,  a live seismometer so kids can "make a quake," and a video tape showing how to use a GPS receiver with USGS topographic maps.


Maps and publications:  USGS maps and reports covering the entire country may be purchased at the ESIC.  Topographic maps are sold for $6 and you may pay by credit card.   There is a 40% quantity discount available for school orders.  There are also many free brochures, booklets and fact sheets on earth science topics, and several free Teaching Packets are available to teachers.  A list of these publications is on the USGS website:

Significant Earthquake Posters on the Web

Each poster in the Significant Earthquakes series contains multiple panels showing the epicentral area, plate tectonic environment, earthquake history, and generalized seismic hazard of the region. These posters are approximately 36 inches wide by 24 inches high.

The posters should be considered preliminary. They are neither completely definitive (the earthquake data are those available in the first few days after the event) nor totally accurate (the map base may contain obsolete information, for example).

The posters may be downloaded for viewing or for printing on a color plotter. Adobe PDF (.pdf) format files are provided. Adobe Acrobat 5.0 or higher is required for viewing the PDF file on a computer monitor and for printing the PDF map graphic. IMPORTANT: The PDF map graphic was produced using TrueType fonts; change the following setting to:
