Ancient Volcanoes of the Mid-South

Between 80 and 70 million years ago the South Eastern United States was a shallow sea.

 

A line of three volcanoes grew into islands. It may be associated with an ancient hot spot that was dragged west to east by continental drift.

 

These three volcanoes are at Monroe, LA, Midnight, MS and Jackson, MS. This area has been extensively explored by the oil and gas industry.

 

I have no heat data for the Monroe and Midnight volcanoes but- Jackson is indicated in red because there is still significant heat down there. Groundwater at depth is in excess of the boiling point. It would be interesting to explore the other two sites to see if there in still heat rising from their magma chambers. 

 

This heat has no where to go. Its trapped thown there and may provide access to geothermal power.

Geothermal power may be an important answer to our future energy needs. All you need to produce electricity is to boil water to drive a turbine. 

 

Our difficulty is with fuels- coal, gas, oil and nuclear power all have downsides. Geothermal energy, if we can figure out how to utilize it, would have none of the down sides of fossil fuels or nuclear power. 

 

Regardless of where you stand on climate change, this is a problem that we need to solve. A power source that like geothermal energy that can't be depleted and doesn't pollute is very promising.
