This Walker Mountain Road home was built on the site of the former Green Mountain House after it burnt in 1866. The link above brings you to the 1976 historical survey where this property can be found as map #6. The survey indicates it was built ca. 1890 but the owners (in 2017) believe it was built in 1866 after the fire. The Green Mountain House can be found in the Buildings collection.
