Virginia Master Naturalist Continuing Education webinar, presented by Charlie Grymes (VMN-Merrimac Farm Chapter.)  
Ever wonder questions such as:

• When did the Potomac, James, and Roanoke rivers cut through the Blue Ridge, and where did the rivers flow before that?
• Why is there salt at Saltville, gold at Goldvein, and coal in Chesterfield County?
• Why is Giles County so worried, when the last major earthquake in Virginia was in Louisa County? 
• Why aren't energy companies considering fracking for natural gas near Virginia's current oil wells? (yes, we have oil wells...)
• Is the Blue Ridge wearing away and disappearing over time, or are we seeing the mountains get higher?

Geology rocks, of course!  Join us for a webinar investigating some of the fascinating aspects of Virginia's geology.
