 She purchased a 500-acre farm directly across the Potomac from Mount Vernon and next to the Moyaone Reserve, an environmentally conscious planned community.Bolton donated her farm for the creation of the Accokeek Foundation and, with a coalition of organizations that included the Alice Ferguson Foundation, Moyaone Association, and Mount Vernon Ladies' Association, launched an ambitious program to protect six miles of shoreline.This large-scale landscape conservation effort led to the creation of Piscataway Park, the first national park established to "preserve historic vistas."
