Rappahannock Navigation Gold Mine Sites (Spotsylvania)

The canal came first. The Rappahannock Company built it to move commercial goods between Fredericksburg and the upper reaches of the river — a planned fifty-mile system of dams and locks, organized in 1816, that took decades of false starts and flood damage before the navigation was finally completed in 1849. It lasted a few years. The company failed in 1853, and the navigation was abandoned entirely by 1855, undercut by rail.

What remained was the infrastructure of a failed enterprise — and, it turns out, a hillside worth entering. Along the stretch of the Rapidan Canal that passes through the U.S. Gold Mine fields, two mine adits cut directly into the canal bed, leading into the hillside. The Wikipedia record notes they were apparently made after the demise of the canal. The canal never paid. The ground it ran through held something else.

This isn't a single site you can stand in front of. The mine sites are spread across Spotsylvania County, a thematic layer more than a destination — the residue of two consecutive extraction stories, one of them in water, one in rock, neither of them finished.
