Duluth will unveil a marker Thursday that denotes the path of the historic Eastern Continental Divide through town.

The ceremony will start at 6 p.m. at the top of the city’s Town Green across from the Old City Hall.

The divide demarcates the Atlantic Ocean and Gulf of Mexico watersheds. It was used in locating early railroad routes where cities such as Duluth grew and prospered.

Duluth's marker will stand about 9 feet tall, have an 18-inch base and weigh about 3,600 pounds. The front of the marker will have a line showing the direction of the water flow. On the rear will be a map of Georgia that shows the location of the divide.
