The Cardigan quadrangle lies in the west-central part of New Hampshire, between latitude 43°30' and 43°45' north and longitude 71°45' and 72°00' west. Newfound Lake, at an altitude of 586 feet, is the only large lake in the district. The higher sections are dominated by Mt. Cardigan, which rises to an altitude of 3121 feet. 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.
The geology of the Cardigan quadrangle has been studied with special reference to the problems associated with the intrusion of the Kinsman quartz monzonite or porphyritic gneiss. The results of the structural and . . .
