The Sumner Hill Williams Sugarhouse
Most of the sugaring activity is centered around the Sumner
Hill Williams Sugarhouse, designed and built in 1992-1993 by sugaring operations
manager, Sumner Williams, with the assistance of PMRC staff and volunteers and
with donations of materials and services of a number of local companies and
individuals. The sugarhouse was expanded in 1999 to accommodate an expanding
educational program sponsored by Husky Injection Molding of Milton, Vermont. The
building was named for Sumner in April 2000 after an accident claimed his life
in October 1999.
