GeoTours is a collection of self-guided roadside geology trips for the layperson. No previous earth science knowledge or experience is required. This is a new addition and is still VERY incomplete. Check back often for enhancements and additions.
If this is your first GeoTour, or if you feel the need for a bit of general information on the earth sciences, please spend some time in the background section.
