I used to moutain bike to the dam at Indian Run as a kid. The distance between the trail entrance near the road and the dam itself is much longer than I remember. Being on foot didn't help either. I never made it all the way to the dam that day, but did manage to take a few shots on the walk.
The photos were all taken along the Gordon Nagle Trail in Schuylkill County, Pennsylvania. I haven't seen trains on the tracks often but they do run occasionally. The area has seen quite a bit of development over the last few years. The shot below of the hillside being clear cut and excavated is somewhat concerning as the area was great for hiking.
Though it was late December, temperatures have been higher than normal and there is quite a bit of green still visible.
