 Rock Talk

 A Series of Short Geology Videos (5 min to 12 minutes each) created by Dr. William S. Cordua, Emeritus Professor of Geology - University of Wisconsin, River Falls. These videos offer a great way to learn basic geology principles, as well as find out how geologists figure things out using evidence in the field, and in the lab. The focus is on the geology of Western Wisconsin but Minnesota has the same rock formations so it is equally valuable for Minnesota residents.

Subteranean Twin Cities
American Institute of Architects
Subterranean Twin Cities is the very first comprehensive published account of the wide variety of subterranean spaces, such as caves and tunnels, under the Twin Cities of Minneapolis and St. Paul, Minnesota, set in a geological and historical context, based on more than two decades of research by Greg Brick.

EARTHWORKS is the world leading on-line database of career opportunities for geoscientists, oceanographers, marine scientists, ecologists, environmental scientists, plant scientists, forestry/agricultural scientists, archaeologists, geotechnical engineers, geographers, climate/atmospheric scientists, space/planetary scientists, remote sensing/GIS staff and hydrologists/hydrogeologists in the academic, water, upstream oil and gas, civil and mining sectors. We are sure a link to EARTHWORKS would be of great benefit to your site users. 

This link to a image of North America was generated with data from the Shuttle Radar Topography Mission (SRTM). For this broad view the resolution of the data was first reduced to 30 arcseconds (about 928 meters north-south and 736 meters east-west in central North America), matching the best previously existing global digital topographic data set called GTOPO30. The data were then resampled to a Mercator projection with approximately square pixels (about one kilometer, or 0.6 miles, on each side). Even at this decreased resolution the variety of landforms comprising the North American continent is readily apparent.
