Henry's Knob name derives from the Henry family, early settlers of York County who originally owned the mountain and surrounding land. In 1765 William Henry was granted 336 acres (1.36 km²) on the south side of the Little Mountain, as Henry's Knob was then called, and four years later he was granted another 100 acres (0.40 km²). At this time northern York County was still part of Mecklenburg County, North Carolina, and was not ceded to South Carolina until 1772.

In the 19th century the portion of the original Henry estate including the mountain was inherited by a female Henry descendant and was eventually sold out of the family prior to the Civil War.

A company named Commercial Ores mined the Henry's Knob site during the 1950s and 60s. Combustion Engineering acquired Commercial Ores in 1965 and then sold it in 1971. The mountain has been transferred between several property owners since then. ABB acquired Combustion Engineering in 1990, long after mining ceased.

The EPA identified ABB as the "successor of interest" and a potentially responsible party. The agency asked ABB to conduct an investigation of the Henry's Knob site and surrounding area to identify pollution, including the nature and extent of acid mine drainage that has entered the environment as a result of previous mining activities. The investigation work plan is on file at the Clover Public Library, along with other documents pertaining to the site.
