 Located in the Upper Schoodic Peninsula sub-region of Maine's Downeast Acadia region, the Municipality has had several incarnations as Waukeag, New Bristol, and later Sullivan; and once included nearby communities of Hancock, Sorrento, and what would later be (parts of Gouldsboro Point TWP, Tunk Lake TWP, the Schoodic Foothills, Hog Bay, and various other districts over time divided off) Township 7, South & Middle Districts.
 Once home to abundant granite quarries, the Town of Sullivan is now regarded as a residential community for nearby Ellsworth and Mount Desert Island, Maine.
 Located along US Rte 1, Taunton River, and Hog Bay, Sullivan is home to a slough of reversing tidal falls and many scenic turnouts that dot the Schoodic National Scenic Byway along the Upper Schoodic Peninsula.

The Point Peninsula Complex was an indigenous culture located in Ontario and New York from 600 BCE to 700 CE (during the Middle Woodland period).
 Point Peninsula ceramics were first introduced into Canada around 600 BCE then spread south into parts of New England around 200 BCE.
 Some time between 300 BCE and 1 CE, Point Peninsula pottery first appeared in Maine, and "over the entire Maritime Peninsula."
 Little evidence exists to show that it was derived from the earlier, thicker pottery, known as Vinette I, Adena Thick, etc..
.
 Point Peninsula pottery represented a new kind of technology in North America and has also been called Vinette II.
 Compared to existing ceramics that were thicker and less decorated, this new pottery has been characterized by "superior modeling of the clay with vessels being thinner, better fired and containing finer grit temper."
 Where this new pottery technology originated is not known for sure.
 The origin of this pottery is "somewhat of a problem."
 The people are thought to have been influenced by the Hopewell traditions of the Ohio River valley.
 This influence seems to have ended about 250 CE, after which they no longer practiced burial ceremonialism.
