possible lead?

Ok guys and gals,

So I have been doing a lot of heavy research in meteorite impacts in Iowa, I have stumbled across another site. I was doing an areal photo view of the site and found this..... it looks like this circular indentation goes all the way back to the 40s, from then back it is covered up by trees so its unknown on if it is there or not. I believe this is potentially an impact site... what do yall think?

The site seem to mirror the bend in the river. Maybe historic flooding. If it was from water movement there could be artifacts left behind.

It's called a meander. Meanders are common on slow moving rivers and streams in flat lands. When a meander changes course the part that is left high and dry is commonly known as an Oxbow or cutoff meander.

You can see an interactive map with all the known craters and meteorite falls on the Land Matters Meteorite Map.

I'm going to assume that you're referring to the bullseye shape. I tried to center it in a screenshot. If it's what you're referring too, I believe it to be vegetative in origin (fairy ring). Only ground investigation could give further information in topography.

No, not the bullseye. I was referring to the meander that's prominent on your aerial photo.
