This observation is for the reddish- and dark brown-colored ants in each photo. These have a suggestion for Formicine Ants. They were crawling around on groupings of decaying, dead Cicadas (for which I will make a separate observation). There is also a carrion beetle in one of the photos (for which I will make a separate observation). Found N or NE of the lake, a ways past the start of the Sunset Lake Trail (going counter-clockwise on the loop) at Glendalough State Park.
