Another season of archaeology underway! Posted June 7, 2024 The sixty-sixth season of archaeological excavation at Michilimackinac began on May 28. This season will be a continuation of the trader’s house we have been excavating since 2007.Southeast cellar floorboards and wall planks. One of the reasons the project has taken so long is that the house has two cellars. We are nearing the bottom of the east section of the southeast cellar; the west section was completed in 2021. Several of the cellar wall planks and a floorboard were exposed at the beginning of the season, but we are in the process of removing them. Only a few houses at Michilimackinac have two cellars. We believe this is the sign of a successful trader with a lot of merchandise to store.Blue and white tin-glazed earthenware bowl. Our other focus for the summer is excavating the area of the north wall of the house and the porch. Parts of the British-era north wall trench are beginning to appear. If this house follows the pattern of previously excavated units of the Southeast Rowhouse, the French-era north wall trench will be slightly lower and to the south of the British-era trench.Fragment from a scratch blue stoneware vessel. One of the characteristics of this house in previous seasons has been the variety of ceramics recovered. This season has been no exception. So far, we have uncovered a piece of a blue and white tin-glazed earthenware bowl and a base fragment from a scratch blue stoneware vessel. The excavation will continue daily, weather permitting, through August 17. The site is located just south of the parade ground within the walls of Colonial Michilimackinac.
The Season Continues Posted July 20, 2023 Fragment of a white clay smoking pipe stamped with a maker’s mark. The first half of the 2023 Michilimackinac archaeological field season has flown by. The cellars continue to yield interesting artifacts. In addition to the gaming die found during our opening week (Our 65th Season Begins! – Mackinac State Historic Parks | Mackinac State Historic Parks (mackinacparks.com), an unusual white clay smoking pipe bowl fragment was recovered from the north edge of the central cellar. White clay pipe fragments are fairly common, but they are usually plain. This one was stamped with a maker’s mark. The motif is a jumping deer. It was used by a series of Dutch pipemakers in Gouda from 1660 to at least 1776. This is a reminder of the worldwide trade networks of which Michilimackinac was a part.With pieces recovered this year, archaeologists have been able to reconstruct this ointment pot. In the southeast cellar, the most interesting artifacts have been plain white tin-glazed earthenware ceramic sherds. These were able to be matched with some sherds from last season to form an ointment pot. This is the second ointment pot we have been able to reconstruct from the southeast cellar.Pewter button from the 8th Regiment. We also have been working in the northern section of the excavation. At the beginning of this season, most of this area was in the layer of rubble from the 1781 demolition of the fort. Interesting finds from this area include part of a stone smoking pipe bowl, two gilt sequins and two pewter buttons from the 8th Regiment. These are the soldiers who demolished the fort. In some areas all the demolition rubble has been removed, revealing the north wall trench of the building cutting through beach sand. This is easier to see in the west end of the house because a tree was planted in the east of the wall trench in the early twentieth century. While the location of the fort was never forgotten, its interior layout was.The dark area in the photo reveals the north wall trench of the building. The 2023 archaeology season continues through August 19. Visitors to Colonial Michilimackinac can watch archaeologists uncover history seven days a week, weather permitting, until then.
Mackinac Island Airport Archaeology Posted May 29, 2020 Refuse revealed by the stripping of the runway.In September 2011 all of the pavement at the Mackinac Island Airport was removed prior to the regrading and relocation of the runway to correct sinkholes and a hump in the runway. The airport was originally established in 1934. Maps from 1902 and 1913 show that the area was used as a dump. The stripping and regrading exposed and removed several areas of refuse.When examining a dump archaeologically, it is not productive to try to salvage, or even record, every object. Instead the goal is to sample enough artifacts that can be dated to determine the timeframe in which the dump was used. In this case these artifacts were primarily ceramics and glass. In general, the glass suggested a date of the first two decades of the twentieth century, matching the maps. The ceramics skewed slightly earlier, probably because they have a longer use life before being discarded.Example from Grand Hotel when operated by Planter’s (1900-1918).Over four hundred ceramic sherds were collected, including fragments of earthenware, stoneware, porcelain and lots of hotel ironstone vessels. Marked examples from Grand Hotel when operated by John Oliver Plank (1887-1889) and Planter’s (1900-1918) were recovered. Other forms collected include marmalade and mustard containers, a candlestick, matchstick holders, porcelain doorknobs, architectural tile, and electric insulators.Three hundred fifty-six bottles and other identifiable pieces of glass were recovered. These included wine, liquor, beer, mineral water, grape juice and other beverage bottles. Six Michigan breweries were represented: Detroit Brewing Company, Goebel Brewing Company, Koppitz-Melchers Brewing Company and Stroh Brewing Company, all of Detroit, as well as the Grand Rapids Brewing Company and Soo Brewing Company. Other consumer goods included condiments, salad dressing, capers, olives, prescription and over-the-counter medicines, skin cream, perfume, ink, and a variety of cleaning products. These products came from across the Atlantic Ocean and as close as Bogan’s pharmacy on Mackinac Island.Part of an oil lamp.Bottle from Bogan’s Pharmacy.Electricity came to Mackinac Island in 1911. This dump spanned the transition. Both lightbulbs and oil lamp parts were recovered. Fire extinguisher.Metal artifacts are much harder to recognize from just a fragment. In addition to lamp parts, cooking utensils, buckles, horseshoes, and enamelware vessels were recovered. Some of the more obvious and interesting metal artifacts included a fire extinguisher and part of a push lawn mower.Push mower.
