The Wolf Pond monster

From Myths and Legends of Our Own Land, by Charles Skinner:

A snake haunts Wolf Pond, Pennsylvania, that is an alleged relic of the Silurian age. It was last seen in September, 1887, when it unrolled thirty feet of itself before the eyes of an alarmed spectator -- again a fisherman. The beholder struck him with a pole, and in revenge the serpent capsized his boat; but he forbore to eat his enemy, and, diving to the bottom, disappeared. The creature had a black body, about six inches thick, ringed with dingy-yellow bands, and a mottled-green head, long and pointed, like a pike's.

Wolf Pond is in Dauphin County near Dietrich. Coloration-wise and general appearance-wise, this sounds as if it could have been a muskellunge (Esox masquinongy) which, in fact, is a type of pike. However, its size was doubtlessly exaggerated.
