River talk

Come and learn about the rich history of what just may be the oldest river in our neck of the woods.

From noon to 1 p.m. today, archaeologist Susan Mulholland will trace the evolution of the Cloquet River, with an emphasis on the section that cuts through St. Louis County.

A detailed survey of this river segment was conducted in 2012, and Mulholland promises to reveal several archaeological discoveries it unearthed.

Seating for the presentation at the Ruth Maney Room on the first floor of the St. Louis County Heritage & Arts Center (aka the Depot), 506 W. Michigan St., Duluth, is free but limited. It’ll be available on a first-come basis. Feel free to bring a bag lunch and enjoy a complimentary cup of coffee.

Mulholland is the co-owner and president of Duluth Archaeology Center LLC, and she holds a doctorate degree in her field.
