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.

Michilimackinac Archaeology 2021 Has Begun

The archaeology crew at work on opening day.

  The 63rd archaeological field season at Michilimackinac got underway on June 1. This will be our 14th season on our current project, the excavation of House E of the Southeast Rowhouse. The rowhouse was built in the 1730s, rebuilt in the 1760s, and demolished in 1781 when the community moved to Mackinac Island. The house was always occupied by fur trading households, first the household of French Canadian trader Charles Gonneville, and later the household of an as-yet-unknown English trader.

  Despite not knowing his name, we have learned quite a bit about the English trader through the artifacts we have recovered. He supplemented the fish diet everyone ate with pigs and other domestic animals. He owned up-to-date ceramics, including styles developed in the 1770s. He was a snazzy dresser, with ornate buttons, buckles, and linked button fasteners. His trade goods likely included hawk bells and fishhooks.

  Although only half of the houses at Michilimackinac had a cellar, this house had two. We will excavate both of them this summer. At the very end of last season, we got a glimpse of the north wall trench of the house, and we hope to expose more of it this season.

  This house has had many surprises and we are excited to see what this season has in store. Interesting discoveries will be posted on MSHP’s social channels and this blog. Better yet, come visit us in person. We will be excavating every day through August 21 (weather permitting). This year the archaeological field season is sponsored by Mackinac Associates and we are grateful for their support.

A New Season

A New Season

Site almost ready to begin excavation for the season

The end of May brings rain, flowers, insects, and archaeology. While next year will be the 60th anniversary of archaeology at Michilimackinac, this year is the 60th season. We will be back for our eleventh season of excavation at House E of the Southeast Rowhouse. Over the past eleven summers we have excavated the south wall, a root cellar, and chimney collapse, and found thousands of artifacts used by the fur traders who lived here. Highlights can be seen in previous blog posts, and include many types of ceramics, personal adornment items such as cufflinks, buttons and rings, an intact rosary, an intact pocket knife, and two shutter hinges. This summer we plan to excavate deeper in the cellar and expose more of the interior wall exposed last summer.

Nail, straight pin, and window glass recovered from slump

Over the past week, we have removed the straw and plastic that protected the site over the winter, re-established the grid strings we use to map the site, and cleaned up dirt that slumped from the wall of the excavation pit during the winter. Excavation will be taking place seven days a week, weather permitting, from June 5 through August 25. Admission to Colonial Michilimackinac includes the opportunity to watch history being discovered.
