We'll need to see how much silvery hair she has on her gaster, which is best viewed a little from the side and with good lighting. A photograph of the front of the head will also be helpful.
If you've enjoyed using my expertise and identifications, please do not create undue ecological risk by releasing your ants. The environment which we keep our pet insects is alien and oftentimes unsanitary, so ensure that wild populations stay safe by giving your ants the best care you can manage for the rest of their lives, as we must do with any other pet.
Exotic ants are for those who think that vibrant diversity is something you need to pay money to see. It is illegal to transport live ants across state lines.

Hard to get a picture as requested. Does this picture help? Not a good one I know.
Did not notice any silvery (or otherwise) hair on gaster. (The fuzz in picture is from cotton)
Is that info needed to determine if it is a Formica or just whether it is a Fusca (or something else)?
Went out in the afternoon and found four more of these.At least I think they are the same. I have to sit in good light and give them all a good look to see if they are in fact the same species.

Yes, it is Formica sp. for sure. It does look similar to F. fusca. However, F. fusca is not believed to be found in North America per Article p515-529 .
A lateral (side-shot) of her gaster is helpful for identifying specific species of Formica in the fusca grouping.

Just an update that the first 5 queens of this Formica Spp. all now have brood! 3 More test tubes (2 which were caught later) have yet to eclose.
