The park's rocks display glacial grooves and striations left by the retreat of the last ice sheet approximately 14,000 years ago.
The deep quarry pit eventually filled with groundwater, creating a freshwater habitat that does not support fish.
The site was once known as Babson Farm Quarry, operated by the Rockport Granite Company.
The World War II fire control tower was part of a coastal defense network designed to spot enemy vessels.
Halibut Point State Park is situated on the site of a historic 19th-century granite quarry that supplied stone for major coastal construction projects. The landscape features a 60-foot-deep flooded quarry pit surrounded by rugged, glacially-sculpted rocky ledges. Visitors can observe coastal geology, including visible joints and dikes in the granite bedrock. The park offers panoramic views of the Atlantic Ocean, spanning from Crane Beach in Ipswich to the Isles of Shoals in New Hampshire. A concrete fire control tower, built during World War II, remains on the property as a historical sentinel. Walking trails provide access to the rocky coastline, tide pools, and preserved industrial remnants. Birdwatchers utilize the park as a primary vantage point for observing migratory waterfowl and raptors. The visitor center, located in the original Babbitt Farmhouse, houses exhibits on the area's quarrying history and marine environment.
