For those unfamiliar with this unusual artifact, it is the curious triangular holes that are diagnostic of the Viking mooring stones. These holes are essentially identical everywhere: an inch across, 4-5 inches deep, triangular in cross section, with neatly rounded corners. The saga is reviewed in our catalog Ancient Infrastructure.
Cross section of one of the strange triangular holes found in boulders. Note the rounded corners. Drillers and purpose are unknown. |
Our purpose here is to flag a recent article in Ancient American that tells of the discovery of still more of the Viking mooring stones in Minnesota, especially in Pope County. The most interesting feature of this article is the map of Pope County giving the locations and approximate elevations of more than a score of the stones. All lie between 1,100 and 1,400 feet. While small lakes exist at these elevations, the stones are all more than 500 feet above Lake Superior. If the Vikings did somehow penetrate into the Great Lakes (perhaps via Hudson Bay or the St. Lawrence), how did they ever raise their vessels 500+ feet to levels of the supposed mooring stones?
There must be a better explanation for this ubiquitous phenomenon.(Pederson, Leland; "Viking Mooring Stones in West Central Minnesota," Ancient American, no. 33, p. 25, 2000.)
Comment. Stacked against the Viking-mooring-stone theory are the stones' presence far inland and at high elevations. Yet, the unusual cross sections of the holes, their precision, and standard dimensions militate against the blasting-hole theory proposed by skeptics.
