First a little history lesson:
"Only a few miles southwest of Fairfield rises one of the larger mountains in the lower Adams County area, called Jack's Mountain, a part of the South Mountain range. Much local history occurred on the slopes, at the foot of, and in the valley adjoining Jack's Mountain. Its name apparently came from a local settler by the name of Jack.
The Adams County Historical Society records show that James Jack was an early tavern keeper in Hamiltonban Twp., being licensed to sell liquor from 1769 through 1773. He died December 23, 1779. His will was proved on September 8, 1780 in what was then York County. His will named John Jack and Benjamin Reed of Hamiltonban Twp as executors. He left a wife, Agnes, 2 sons, John and Andrew, and 7 daughters, Elizabeth, Jean Wilkey, Agnes Kenahan/Kernahan, Ellaey Reed, Sarah Reed and Easter/Esther/Hetty Wilson. Jack's Mountain may have been named for him or one his descendants. His sons and their children moved away sometime after his death. There was no one named Jack in the 1802 assessment roll of property owners and single men in Hamiltonban Township.
One of the earliest land grants containing the name Jack's Mountain was issued in 1792 to Dr. James Crawford. This grant was for two land sections on top of Jack's Mountain totalling 41 1/2 acres, and joined together by a narrow land corridor. A probable explanation for this grant was the establishment of a base for the extraction of ores or minerals.
Atop the southwest portion of Jack's Mountain, a Mr. Thompson mined low-grade copper ore which ws not commercially profitable. This was the plight of a number of other copper mines in this vicinity. However, just west of Iron Springs, iron was successfully mined and smelted, and manufactured items, such as stoves, were produced at Maria Furnace from 1826 to 1838.
As with all mountains, this one got in the way of the people trying to get around. However, travel and transportation networks did develop to bring them together."
