The Invisible Forge Why Blacksmithing Occurred on Oak Island Without Leaving a Forge Author: Jerald Lee Harrah

Oak Island has yielded numerous forged iron artifacts dating broadly from the late medieval to early modern period, including ox shoes, spikes, fasteners, and tools. Despite this, no clearly identifiable blacksmith forge, hearth, or slag concentration has been conclusively documented. This absence has often been interpreted as evidence that blacksmithing did not occur on the island. This paper argues the opposite: that the archaeological pattern present on Oak Island is precisely what would be expected if blacksmithing did occur but was conducted using temporary, non-permanent methods and intentionally dismantled prior to abandonment. By examining early modern blacksmithing practices, military and naval logistics, construction methods, environmental processes, and post-occupational disturbance, this paper demonstrates that the lack of a forge is not an anomaly but a predictable outcome of deliberate erasure and long-term site transformation.
