I'm curious to see what this
I'm curious to see what this is. I'm guessing Pogonomyrmex, but the ones I know are generally docile. I think fire ants can be eliminated.

 
Yes, I would say Pogonomyrmex
Yes, I would say Pogonomyrmex too. These particular ants were found on a river bank. They did seem more aggressive than your typical harvester ant. So what kind?

 
Definitely a pogo,
perhaps P. occidentalis. Many harvesters are known for their nasty stings.

 
Either occidentalis or salinu
Either occidentalis or salinus would be the two best choices.
