[email protected]. B6-1 207 THE GEOLOGY OF THE SADDLEBACK MOUNTAIN AREA, NORTHWOOD QUADRANGLE, SOUTHEASTERN NEW HAMPSHIRE Laura R. Whitaker Department of Geology The College of Charleston Charleston. SC 2942^ Introduction Saddleback Mountain is a four-peaked saddle-shapped mountain located 39 km west of Portsmouth, NH (Figure 1). The mountain lies along the boundary between the New England Uplands and the Seaboard Lowlands Sections of the New England Physiographic Province of Fenneman (1938). It also lies adjacent to the western boundary of the Massabesic Gneiss Complex as designated by Anderson (1978). Figure 2 of this text is a generalized Geologic Map of Southeastern New Hampshire compiled from Billings (1956) and later workers cited in the references from Figure 1. Portions of Figure 2 show that the Saddleback Mountain area is on strike with two convergent fault zones which are postulated to be of regional tectonic significance: the Nurambego of southern Maine (Hussey and Pankiwskyj, 1976; Hussey and Newberg, 1978), and the Pinnacle-Campbell-Hill-Hall Mountain Faults mapped by Camein (1976).
