Introduction

A Landmark That Time Has Not Forgotten

Near the small community of Mineola, travelers on Interstate 70 pass a weathered sandstone formation known locally as Slave Rock, and also as Graham Rock — from Dr. Robert Graham, a nineteenth-century slaveholder whose property once included the site.

For generations, local tradition has connected the rock to the sale of enslaved people before the Civil War. That account is part of the region’s oral history — but it has not yet been confirmed by documentary evidence, and this project presents it as tradition, not established fact.

Here you’ll find what is known, what is told, and what remains to be discovered.
