Olmsted Walking Tour of Anderson Park. Before Anderson Park existed, three houses and a fire station sat on the property. Find out where they went and other surprising stories about how this Olmsted-designed Essex County park came to be created over a century ago, how it shaped Upper Montclair, and how it led to the formation of other Montclair parks. Also hear about efforts to rejuvenate the landscape of this park, on the National Register of Historic Places. FREE. Meet at the boulder at Anderson Park's northeast entrance, 274 Bellevue Avenue, east of North Mountain Avenue, Upper Montclair. Sponsored by Friends of Anderson Park.
