Although this mountain and a few neighboring summits are barren, the higher sections in most of the area are heavily wooded. Danbury, Alexandria, Hebron, Orange, and Grafton are small farming centers within the quadrangle. Three large towns lie just beyond the boundaries—Plymouth, three miles to the northeast; Bristol, one mile southeast; and Canaan, one mile west.
