 The river forms the boundary to the west, and the inland boundaries are generally the result of steep slopes along the river bank or of the streams that pass through the area.The village's northern boundary is distinguished by a transition to later industrial development of Cobalt village, and to the south by a wooded open space and a more widely spaced development pattern.The district has 58 historically significant primary buildings, most of which were built before 1835, giving the village a distinctly Federal style.
