The Trail Through Time is a bi-cultural heritage trail through the North Acton conservation lands that provides access to Colonial and Native American sites. The Wheeler Farm and (Robbins) Mill complex and its surrounding area show evidence of the interaction between the Native American and the early Colonial cultures that to some extent existed concurrently. This Phase III project will focus on stonework restoration of the Grist Mill complex together with landscaping enhancements and information panels. It is designed with future enhancements to the Native American artifacts in mind.
