Back when I lived in Jersey I would take the commuter plane out of Atlantic City to Philly once a month. Winter was the best time to see old roads, walls and revolutionary fortifications. On the Jersey side is of the Delaware River across from the airport are small stone fortifications big enough for a couple cannons facing the river. River access would be the only way to see it up close as there was no road through the swamp behind it. I'm sure there were others, but that is what I could see from the plane.

There appears to be parallel lines running from upper left to lower right.
Are they due to glacier action or something else. (Like giants sledding down from Canada.)

Two 18 pounders and two 9 pounders.

Yes, glacier tracks.
