If you click on the image, you can see the ants better--they were very long. Sorry for only having one shot. They weren't very happy about me moving their rock. I had planned to remove a lot of rocks from around my flower bed, but one half the garden had these under it and it appeared to be one "nest" that was connected. I'd hate to think how big this colony actually is!! My flower bed is about 10ft by 5ft, so that's one huge nest! I finally gave up.
