It's one of the most contentious issues facing Upstate New York and other parts of the country sitting over resource rich reservoirs like the Marcellus Shale and the Utica Shale: hydrofracking.

Proponents say extracting these natural gas and petroleum will grant the United States more energy independence.  Detractors of the practice say it's too damaging to the environment.

In New York State, hydrofracking is practiced most often in the Marcellus Shale laying under the counties of the Southern Tier.

What exactly does a hydrofracking well look like?
