Any idea what these symbols are on these old 1930's aerials?

The 2 symbol one is on the top of a 50 foot hill.
The 4 symbol one is by a 15 foot ravine with a creek going through it.

Thank you!

Do those marks appear in the same spots on a topo map of the area? I don't see it in the USGS guide for maps (link below) but it could be some kind of control like the ones listed for "horizontal control". An easy way to tell if it is just related to the photo or of the mapping area would be if it is on both. I am assuming its a control for the images.

Have you looked at the same areas on todays Google Earth? Do that and tell us what you see.

I couldn't find anything remotely resembling those symbols, so I'm just going to toss out a wild guess...

1- being in a ravine and on a creek, some sort of Mill.

2- Looks like some sort of transmission tower. if there are no others (such as for electrical or telephone), then I'd say Radio.

Again, those are simply guesses with absolutely nothing to base them on.
