Here's a larger version of that map. The area above the blue band near I-80 is of interest to gas companies, while the highest interest is in the peach section at the top.

And another geological map showing surrounding counties...

There's outcropping in the purple part near Washingtonville. And the "Jerseytown Coal Mine" is in the blue part just north of there. In the 1800s, they thought the black shale was coal.

Could there be a quick break down on what the other colors mean ....trying my best to see on the Geological map but can't make the rest out.

Hi Tom My land is in the strip of peach right below the 1st big orange area.IS that should be a good area?? Also is that theroy proven or still just theroy?? I know 50 sixty years ago my land was checked for coal. there wasn't any there . Neighbors and preivous owner told me and parts of the holes you can still see. Is that a good thing?? Sorry for all the questions . This is the one thing I didn't quite understand . A year ago I got a letter from Mason Dixon about the gas. They later said they weren't coming here at that time. Thanks ken

I'm not a geologist and even the geologists don't apparently know everything. They have to do extensive testing from helicopters and thumper trucks to get a good idea of the mineralization. And then they drill test wells, and they don't always hit what they want. But clearly it makes sense that if the layer which would contain the shale outcrops to the surface, then there isn't likely any gas there. That much they know and is documented. My admittedly amateur take is that there's probably some gas in most areas starting a few miles north of the blue band near I-80. The further south you go toward that band, however, the riskier it is. So maybe the gas companies will eventually get there, but they want to start up at the top of the county and work down. They know there's good gas up there, and they can progressively move south until their holes start becoming unprofitable. That said, they may offer leases just to tie up the land so that others can't get it. It may be at less lucrative terms as in the north however.
