The installation Confluence, sited on the Assabet River Rail Trail in Maynard Center overlooking the Assabet River, was created by artists Laurie Bogdan and Kimberley Harding. Depicting the convergence of three Massachusetts rivers, Confluence illustrates the issues of human impact on Massachusetts waterways. The extremities depict the pollution from the textile industry, mercury build up, and the excess silt and algae bloom caused by climate change. The rivers’ convergence in the center provides a brighter, more hopeful view, portraying local efforts to mitigate the damage. Since the 1970s efforts to improve the water quality and quantity, preserve habitats, and deal with invasive species have made improvements, but there is still much work to be done. As the Sudbury, Assabet and Concord rivers converge, so should their neighbors also unite to preserve and improve all Massachusetts Waterways.

In a year-long collaborative public art project by Minute Man National Historical Park and The Umbrella Arts Center, invite you to explore the beauty, history and unique nature of the park through creating and sharing public art. Each season we issue simple seasonal prompts on printable activity and learning sheets challenging everyone with access to a pen, pencil, marker or crayon to share a 'work of art' inspired by the Park via social media. Our current challenge -- to imaginatively fill in the picture surrounding the Old North Bridge -- site of the "shot heard 'round the world" -- is a great challenge for those visiting the area for Solstice. Pick up your sheet at The Old Manse, The Umbrella, or download it at TheUmbrellaArts.org/ONE then share your creation with hashtag #OneRevolutionArt, tagging both @MinuteManNPS and @TheUmbrellaArts. We'll be exhibiting collected work all year!
