Geology Links

This page will be updated at frequent intervals as we accumulate more web links. If you know of any links that you feel would be valuable to the Geology Department, please e-mail them to Jennifer Kruse.


Rocks and Minerals

  • Foss Web. Database of images for common rocks.
  • Web Mineral. Great resource for information and images of minerals.


  • USGS Earthquake Hazards Program. The main source for current and historical earthquakes in the United States, though coverage of earthquakes is global.
  • IRIS global seismic monitor. Shows locations of earthquakes globally over the last five years. Great resource for current earthquakes and you can link to see seismometers around the world.
  • Virtual Earthquake. A website designed to teach the fundamentals of earthquakes and seismology. This is used in the Principles of Geology (GEO 111) class at Gustavus.


Graduate Schools in Geology

Most universities have graduate programs in geology. (Note that many programs have recently changed their name to Earth Science, or Earth and Environmental Science.) Here are a few that our recent graduates have attended, but there are dozens more to explore and choose from.

Professional Societies

  • Geological Society of America (GSA). Homepage of the GSA; this contains links to meetings, publications, grants, members and information for students from the GSA.
  • American Geophysical Union. Homepage of the AGU, the largest society of geoscientists in the world. This site contains links to meetings, publications, grants, members and information for students from the GSA.
  • GSA Quaternary Geology and Geomorphology homepage. The QG&G is the second largest division of the GSA. This site contains information about Quaternary research by GSA members, funding opportunities and activities of the GSA.
  • American Quaternary Association. The AMQUA is a small society of geoscientists that studies many aspects of the Quaternary Period. This site contains information about upcoming meetings, benefits of membership, job opportunities and announcements of the AMQUA.
  • The International Union for Quaternary Research. The INQUA is similar to AMQUA, but includes a much broader membership that spans the globe.
  • Association for Women Geoscientists. An organization for women geoscientists to promote participation of women within the geosciences and future careers.

Federal Links

Geographical Information Systems (GIS)

  • GIS data depot. This site contains abundant GIS data from around the world, although most available data are from the U.S.
  • Minnesota GIS data. Site supported by the Minnesota DNR, digital elevation models can be downloaded for free.
  • NOAA GLOBE project homepage. The national elevation dataset, large-scale digital elevation models can be retrieved here.

Geological Time

Topographic Maps

  • Visualizing Topography. This site is designed by a Stephen Reynolds (Arizona State University) and provides several practice exercises for interpreting topographic maps.
