I've counted eight anthills in the area, at least close to the path. At least three of them about 8-10 feet across, which is about the maximum for their kind. There's probably more. This one was the only one i saw that took advantage of a collapsed tree for structural purposes when building the nest.
All of them formica rufa, red forest ants. They're freaking awesome - eat anything up to the size of mice, if they find a dead one. Do not touch - even a single bite itches, and these hills have up to 5 million of the little ones living in them.
