This goes back a few decades, but since you probably know the local area well, I can be specific. If you are driving County Road 347 away from Jewett and toward Concord, after crossing the BN-SF railroad, the road first goes down a hill and then up the next hill. Assuming nothing has changed over the past 20+ years, toward the top of that hill on the left is a private road that goes to what is now called Rose Lake. (That might be the same road the drilling crew is using, but I couldn’t tell for sure from your photo.) The coal outcropping is in the field to the right of the private road, between the road and the fence to the Golie place, and between CR 347 and a barn a few hundred yards away that we stored hay in. I discovered it when I was a boy walking that field hunting rabbits with my 410. At the time it was just a small (few meters) area a few inches high where coal was exposed. I remember it so vividly because I hadn’t seen coal anywhere else on our place and when I told my father about it, he had me show it to him. I now know that East Texas has coal, so it wasn’t such an anomalous discovery but it seemed like it back then.
Is coal common in that part of Leon County?
