Sweetwater Creek before the trail fills
A brick mill shell standing in a wooded gorge, and a ninety minute window before it becomes a busy state park.

The ruin is a mill, and what is left of it is one long brick shell with five floors of empty window openings and nothing behind them. It stands on a slope above a creek about half an hour west of Atlanta, inside a state park, and it is reached by a graded trail with steps in the steep sections.
It burned in 1864 and was never rebuilt. The walls have been standing open to the sky for a hundred and sixty years, which is long enough for the brick to have gone soft at the edges and for trees to have grown up tight against the outside of it.
Why the hour matters here more than the light does
This one is not really about a light effect. It is about having the place to yourself.
Sweetwater is a popular park close to a large city, and the trail to the mill is its main attraction. By ten on a Saturday it carries a steady line of people in both directions, and the ruin has somebody in every window opening. That is entirely fine and it is what a state park is for. It is also a completely different place from the one that exists at seven.
At seven there is nobody. The creek is loud, because a creek running over rock shelves is always loud and there is nothing else making noise. The shell is dark inside while the sky above it is already pale. You can stand in the middle of the trail for ten minutes and hear only water.
The subject here is not the ruin. It is the ninety minutes in which the ruin is not a photograph everyone already has.
What the light does
The gorge runs roughly east to west, with the ruin on the north side, so the first sun comes over the ridge behind you and lands on the far slope first. For a while there is a bright wall of trees on one side of the creek and full shade on the other, which is difficult and not very interesting.
The good part comes when that line drops far enough to reach the top courses of the brick. The upper floors light warm while the base of the wall is still in shade, the window openings go black, and the whole structure reads as height rather than as a flat face. It lasts perhaps twenty minutes.
In October the leaf colour on the slope behind the wall lifts everything and the creek runs low and clear. In summer the same view is a green wall with a dark shape in it and the water is high. Autumn is worth waiting for here in a way it is not on the river.

The ground
The main trail is well made and easy in daylight. In the dark it is a different proposition: it is rock, root and stone step, all wet with dew, and the steps are uneven in depth. This is a trail to walk with a torch and without hurrying.
The rock shelves in the creek below the ruin are the actual hazard, and they are the thing people are drawn onto. Wet, algae covered rock in moving water is treacherous, the drop between shelves is enough to break a leg, and people have died in this creek. There are signs saying so. At seven in the morning with nobody around, ignoring them is worse than ignoring them at noon.
Stay on the trail and on the platforms. The view from the trail is the view.
Getting there and back
The drive out of Atlanta at six is fast and the drive back at nine is not, which is the reverse of what people expect. Leaving the park by half past eight puts you back in the city before the worst of it. Staying until ten costs an extra forty minutes on the way home and gains a busy trail.
There is a decent argument for staying anyway, walking the longer loop above the ruin, and letting the traffic sort itself out. That loop is quiet even when the mill is not.
Was it worth the alarm
Yes, in autumn, and it is a close thing in summer.
The honest position is that the mill is a fine subject at any hour and the early start buys solitude rather than a better photograph. Whether that trade is worth an alarm at five is a personal question. For me it was, twice, and both times the thing I remembered afterwards was the noise of the creek in an otherwise silent gorge rather than anything I brought home in a frame.
