Clark County’s latest historical marker will be unveiled Friday to commemorate part of a 40-mile trace used by settlers at Fort Boonesborough.

The marker, which will be installed near Hall’s on the River Restaurant, will signify the Salt Springs Trace, which local historian Harry Enoch said is part of a trail settlers used to make salt in the late 1700s.

The trace ran from Fort Boonesborough to Lower Blue Licks in present day Fleming County, and is part of a buffalo trace. Early settlers found the trace shortly after arriving in the spring of 1775, Enoch said.

“They would go to Lower Blue Licks to hunt and make salt,” Enoch said of the fort’s residents. “It’s where (Daniel) Boone and his salt workers were captured in 1778. Boone escaped and got back to the fort in time to warn them the Indians were amassing. That’s when they brought 400-plus indians to the fort and besieged them for 10 days.”

In Clark County, the trace ran through the current Lower Howard’s Creek Nature Preserve. Portions of it were restored to hiking condition with funds from a $601,000 state Transportation Enhancement grant several years ago, Enoch said.

The unveiling will be at 5 p.m. Friday at Hall’s with a reception to follow. Enoch said the marker will be unveiled by members of the Society of Boonesborough, whose members are descendants of those who lived at the fort.
