Natural Features & Ecosystems
(Daniel Noon, NPS)
Saugus Iron Works National Historic Site contains many types of natural features. The most dominant of these features is the Saugus River, which flows through the middle of the historic site. The Atlantic Ocean, which is located approximately three miles downriver, plays an important role in the habitat and biodiversity within the Saugus River by regulating the level of salts and minerals in the water through changes in the tides.
Did You Know?
“Saugus Jasper” is a unique material found only in Saugus, MA. Thousands of years ago a small outcropping near Saugus Center provided Native Americans from all over New England with tools. However, Saugus jasper is not truly jasper. Saugus jasper is actually a type of rhyolite.
