Michilimackinac Archaeology 2021 Wrap-Up

Southeast root cellar. This image shows the cellar shortly before completion. Only a gray circular area of cultural deposit, probably a postmold, and remnants of the south wall remain. 

  The 2021 Michilimackinac field season came to a satisfying end in late August. After seven seasons of excavation, we have finally reached the bottom of the southeast root cellar! The cellar was first tentatively identified in 2015. Since that time remnants of the north, west and south walls have been exposed and excavated along with a wide variety of interesting artifacts. More cellar deposit and the east wall are still present in the east profile and extending into the area of the House D excavation where the cellar was identified, but not excavated.

Central cellar. The dark soil surrounded by lighter sand is the central cellar. Six posts are now visible along the eastern edge of the cellar, two on the south, three on the west, and one on the north.

  The central cellar, on the other hand, became better defined and shows no sign of ending. It continued to yield trade goods, such as hawk bells, and structural artifacts, such as a hinge.

  A second new square was opened in the north row of squares where we eventually expect to find evidence of the north wall of the house. Both squares opened this summer are now down to the rubble layer created by the 1781 demolition of the fort.

  The newest square yielded the most interesting artifact of the second half of the season, a clear, circular intaglio set with Masonic symbols on it. The square and compass surrounding the letter G are easy to see. The surrounding symbols are not as legible but appear to include a trowel on the left. The set is .42” in diameter and could be from a linked button or a ring.

  While the lodge at Mackinac (St. John’s #15) was not established until 1784 on Mackinac Island, many of the soldiers and traders at Michilimackinac were members of lodges in Detroit or further east. Known Masons at Michilimackinac include: Major Robert Rogers, Lt. John Christie, Captain John Vattas, Lt. Robert Brooks, Lt. George Clowes, Surgeon’s Mate David Mitchell, Felix Graham, Benjamin Lyon, Forrest Oakes, David Rankin, and Ezekiel Solomon.

  This list is a starting point for possible owners of the intaglio. It could be a clue to the “British trader” who owned the house or could have been lost by a guest of his. It is particularly interesting to note that three other residents of the southeast rowhouse were Masons, Lt. Clowes (House A/B), Ezekiel Solomon (House C), and David Mitchell (House D).

The site is packed and waiting for spring.

  The 2021 field season was sponsored by Mackinac Associates, and we thank them for their generous support.

Preparing for the Season

Preparing for the Season

The site (between the barrels) buried under several feet of snow.

After the spring melt.

Ready to excavate.

Spring has sprung in the Straits of Mackinac region, and with spring comes the preparation for another archaeological field season. Regular blog readers will remember that at the end of last season we lined the site with heavy plastic sheeting and bales of straw. The long snowy winter was very good for preventing the wall from slumping too much. When we removed the straw and plastic last week, the site was in fairly good condition. (more…)

Winter in the Lab

Winter in the Lab

The long winter has given the archaeology staff plenty of time in the lab to process and catalog the artifacts from the over 500 separate contexts excavated at Michilimackinac during the 2018 field season. A context is a single soil type in a tenth of a foot level in a 5’ x 5’ square. (more…)
