The Summit Hall Farm smokehouse, standing on the ridge of Summit Hall Farm, is regarded as the oldest complete historic structure within the City of Gaithersburg and serves as a reminder of the early settlement of Log Town. Although its exact construction date is unknown, it may be associated with a succession of prominent owners of Summit Hall, or Zoar, including Baltus Fulks in 1773, Colonel Edward Burgess in 1783, Thomas Beall of George in 1799, Jacob Swamky in 1807, James DeSellum in 1828, Catherine and John DeSellum in 1847, I. T. Fulks in 1886, Frank and Nettie Wilmot in 1936, and the City of Gaithersburg in 1982. Approximately 14 feet square, the building rests on a fieldstone base, retains its notched logs and chinked mortar, and originally had a roof of rough wood shakes later replaced with machine cut wooden shingles. Its purlins and ridgepole were also replaced with modern lumber and plywood sheathing, and its short wide east door, made of three wide planks nailed to two interior horizontal members, was first designed with a loop leather hinge and peg salt-resistent iron hinge system but is now mounted with wide triangular iron strap hinges. A concrete floor was added to the interior, though the center section can be removed to expose the original fire pit, and in 1990 the City of Gaithersburg commissioned Dell Corporation to make restoration repairs.
