As archaeologists prepare for the start of the 2026 field season at Colonial Michilimackinac, an unexpected discovery is already generating excitement.

During routine cleanup and site preparation work ahead of this summer’s excavations, researchers uncovered a brass jaw harp in the central cellar of the Southeast Rowhouse excavation site. The find offers another intriguing piece of the puzzle as archaeologists continue their long-running investigation into one of the fort’s most fascinating households.

Jaw harps, small handheld musical instruments played by plucking a metal tongue while holding the frame against the teeth, were common trade goods in the 18th century. While the latest discovery is noteworthy on its own, it is even more significant because it marks the thirteenth jaw harp found in the same area of the Southeast Rowhouse.

All 13 jaw harps recovered from the site have been found either in the central cellar or in adjacent excavation squares, raising new questions about how the building was used during its occupation.

Researchers say there are several possible explanations for the concentration of instruments in this area. One theory suggests the central cellar may have served as storage for trade goods, while a separate cellar in the southeast portion of the house was reserved for food and household supplies. Another possibility is that the central cellar predates the southeast cellar and dates to a period when jaw harps were particularly popular during the French occupation of Michilimackinac.

For now, archaeologists say additional research will be needed before drawing firm conclusions.

The 2026 season marks the twentieth year of excavation at the Southeast Rowhouse, a building that served as a trader’s residence throughout its history. The house was first occupied by French trader Charles Gonneville before later becoming the home of an English trader whose identity remains unknown.

Artifacts recovered over the years suggest the English resident enjoyed considerable success. Excavations have uncovered bones from expensive domesticated animals, imported English ceramics, ornate buttons, decorative buckles, and other personal items that point to a prosperous lifestyle.

Visitors to Colonial Michilimackinac will once again have the opportunity to watch archaeology in action this summer. Excavations are conducted in the center of the historic fort and are included with regular site admission.

Archaeologists are scheduled to work on-site daily, weather permitting, from June 2 through August 22.
