A panel of pecked-out human faces, some with horns or rays radiating from their heads, sits on a rock ledge directly above the falls. The carvings are pre-contact, attributed to the Abenaki and probably several centuries old. There are around two dozen figures in all, ranging from a few inches across to over a foot.
The site is reached by a short paved path from the Bridge Street viewing platform; the carvings are in plain view, though weathered. Spring and autumn light is best for picking them out. An interpretation panel gives the basic history but does not pretend that anyone is sure exactly what the figures meant.
