Celebrate the first annual Geologic Map Day! On October 19, as a part of the Earth Science Week 2012 activities, join the American Geosciences Institute (AGI), the Association of American State Geologists (AASG), and the U.S. Geological Survey (USGS) in promoting the importance of geologic mapping to society.
Geologic maps tell the story of each state's natural history through time, what rocks and minerals are there, how rivers and waterways were formed, where landslides and earthquakes have happened, and much more. Learn how to make geologic maps and how to read and understand them on Geologic Map Day. Go to http://www.stategeologists.org/ and click on your state to find your state's geologic map and educational materials about your state's geology.
"In Minnesota we use geologic maps to keep our drinking water safe and to show why we have sinkholes. They are a brilliant tool to answer questions about the land and water posed by everyone from students to our state and national leaders" notes Dr. Harvey Thorleifson, President of AASG and State Geologist of
Minnesota.
Additional resources for learning about geologic maps can be found on the AGI Geologic Map Day web page (http://www.earthsciweek.org/geologicmap/). Earth Science Week 2012 will be celebrated October 14-20. To learn more, please visit
