Mount Jackson is a summit in New Hampshire’s White Mountains, part of the Presidential Range between Mount Pierce and Mount Webster along the western edge of the Presidential–Dry River Wilderness. Named for Charles Thomas Jackson, New Hampshire’s state geologist in the 19th century, it occupies a prominent place on one of the state’s best-known ridgelines. The mountain helps connect Crawford Notch with the higher northeastern summits, and the Appalachian Trail crosses its top while following the main crest of the Presidentials from Georgia to Maine. As a result, Mount Jackson is both a notable destination itself and part of a classic high-country traverse toward Mount Washington.
