Granite pegmatite. Hall's Ridge, Plumbago-Puzzle Mountain. - Oxford pegmatite field. Originally a prospect for feldspar, but shown to be uneconomic. Later explored by Summit Exploration Company (2006) with similar results. The pegmatite appears increasingly sheared and granulated towards the northwest near the Plumbago Mountain Fault separating Halls Ridge from Plumbago Mountain, itself. Howe Brook follows the northeastern trace of the Plumbago Mountain Fault. (Locality has been erroneously cited as being in Newry, but it is actually located just across the town line in Rumford.)
