We found this Red Ant, Myrmica sp., nest under a stone. The chamber in the middle of the photo had many workers tending larvae, and what appeared to be a queen, a bit larger with darker head on the top left corner. With the ants, there were a few Cyphoderus albinus, a species of white springtail which is often found inside ants nests. There were also many millipedes, thread-like, blind, with red spots, Blaniulus guttulatus.
