The M&N constructed the 2.13-mile High Cliff Spur in 1891. It ran from High Cliff Junction to the lime kilns at High Cliff, Wis. High Cliff Junction was Milepost 7.3 on the Menasha Branch.
It became part of the Superior Division of the Chicago, Milwaukee & St. Paul (CM&StP), or Milwaukee Road (MILW), after they took over the M&N in 1893. The MILW reorganized as the Chicago, Milwaukee, St. Paul & Pacific (CMStP&P) in 1928.
The MILW abandoned this spur in 1957, about a year after lime production ceased.
