Bull Brook originates in Willowdale, crosses Linebrook Rd. and merges with Dow Brook at the Ipswich Utilities site on Rt. 1A. From that point the combined stream becomes the Egypt River.
in the early 1950’s, a group of young amateur archeologists men discovered one of the largest Paleo-Indian sites in North America along the banks of Bull Brook and the Egypt River in Ipswich, with over 6,000 artifacts uncovered.
