The Williamstown Historical Museum is hosting an illustrated lecture about the Forgotten Ledge of Fort Massachusetts for children and families at 11 a.m. Saturday, Sept. 24, at the Milne Public Library.

Led by Wendy Champney, the audience will follow the clues as they reveal the location of Indian Ledge and uncover its lost history.

Audience members will also discover the significance of the relationship between the ledge and the 1746 attack on Fort Massachusetts located in present-day North Adams.
