A Closer Look at the Collections: Cameos Posted April 7, 2023 One of the next major projects for Mackinac State Historic Parks will be the reconstruction of a unit on the Southwest Rowhouse at Colonial Michilimackinac. To prepare, MSHP staff have been going over the archaeological records and artifacts from the 1960s, when the unit was originally excavated. Today, our Curator of Archaeology, Dr. Lynn Evans, is looking at a cameo ring recovered in 1962.
Archaeology in Review: Brass Scale Weights Posted March 24, 2023 Weight found in the central cellar.Among the unusual finds from the 2022 Michilimackinac archaeological field season were two brass scale weights. They were found in the cellars of the trader’s house.Nested cups found in the vicinity of the church/blacksmith shop in 1959 The weight from the central cellar was a cup from a set of nesting weights. Of the fourteen brass scale weights ever found at Michilimackinac, all but two are from nesting weights. These are a series of nested cups plus a small solid trapezoidal disc which nests in the smallest cup. The best example of this is three nested cups found in the vicinity of the church/blacksmith shop in 1959. They were fused together in a fire. Over the years four other cup weights have been found. Based on differences in the angle of the sides at least two sets of weights are represented. The recovery of four of the small disc weights indicates a minimum of four sets. The weights are scattered around the fort, with an additional weight from the church, three from the barracks, three from the south southwest rowhouse, one from the southwest rowhouse and one from the Rue de la Babillarde in the southeast quarter of the fort. The cup found in 2022 weighs approximately half of an apothecary dram. It fits into a larger cup weight found in the nearby Rue de la Babillarde. Discs from the barracks, southwest rowhouse and south southwest rowhouse fit into it. We initially interpreted the symbol stamped in the cup as a fleur-de-lis, but further investigation reveals that it is more likely the crossed arrow and key of Nuremberg. Nuremberg was a center of scale making in the seventeenth and eighteenth centuries. The weight from the southeast cellar is unique so far. It is trapezoidal, but much larger and heavier. It weighs an ounce and is stamped “GR” surmounted by a crown. This is almost certainly a reference to King George and indicates British use. The other unique brass scale weight found at Michilimackinac is a small square stamped ½ dram. It was found near the barracks wall in 1959 and is on display in the “Treasures from the Sand” exhibit at Colonial Michilimackinac. What were brass scale weights used for? The small weights are commonly referred to as apothecary weights. It is possible that the weights found in 2022, and the one found in the Rue de la Babillarde were used by Surgeon’s Mate David Mitchell who lived in House D of the Southeast Rowhouse. That would not explain the other scale weights found throughout the fort. It is possible that some of the others were used by merchants to weigh coins or other small but valuable items. In his December 31, 1778 inventory of his personal possessions, John Askin listed:a Weighing Beama smaller Dittoa Comn Weighing Beam old at ye Bakersa Sett of Cast WeightsBaking at Colonial Michilimackinac. The first two weighing beams may have been small balances that would use small weights like this. The last one would have been larger in keeping with the larger measures used by bakers. You can see a large weighing beam in action during the special Askin’s Men and Women at Michilimackinac weekend August 5-6, 2023. The two scale weights recovered in 2022 will be on display in the “Current Archaeology at Michilimackinac” case in the Visitor’s Center when Colonial Michilimackinac opens May 10, 2023.
Archaeological Collections Management at MSHP and the IMLS Posted February 24, 2023 Mackinac State Historic Parks has been conducting archaeological excavations at its sites for over sixty years. This has resulted in the recovery of over one million artifacts and reams of field notes, maps and other documentation of the excavations. Because excavating a site destroys it, preserving these artifacts and records is a crucial part of MSHP’s stewardship mission.Archaeological field records stored in the Petersen Center in Mackinaw City. For many years the artifacts were housed in Lansing, while the records were stored in Mackinaw City. Paper records were microfilmed, with the microfilm stored in a separate location as a physical back-up copy. Today the paper records are scanned instead. In the mid-1990s, MSHP purchased a computerized collections database package. We subsequently received a grant from the federal Institute of Museum and Library Services (IMLS) to enter all the archaeological artifact catalog information into the database. Three data entry clerks were hired for two years to accomplish this task. The biggest gap in the initial data entry project was that the artifacts were still in Lansing, so their exact storage locations could not be entered.Archaeological artifact cabinets in the Petersen Center. With the completion of the Petersen Center in 2001, the archaeological collections were moved north. The vast majority are housed in the Petersen Center, but building materials, such as chinking and nails, which have less strict climate control requirements, are stored at Mill Creek. Once the collection was moved north, staff attempted to update the database with location information, but the task was too big to complete alongside other duties. In 2010 another IMLS grant was secured to hire three inventory assistants. Over the course of two years, they physically inventoried and updated the database record for all the Michilimackinac archaeological artifacts housed in the Petersen Center.Building materials stored at Mill Creek. While the Michilimackinac collection makes up the majority of the archaeological collection, major excavations have been carried out at Fort Mackinac and Historic Mill Creek Discovery Park as well. Last year MSHP received another IMLS grant to inventory and update records for the Mill Creek artifacts and some of the Fort Mackinac artifacts. This grant will also include inventory and re-housing of a portion of the architectural artifacts stored at Mill Creek. This project began in October 2022 and will continue through August 2025.Alex Michnick inventorying Mill Creek ceramics. These grants have assisted MSHP in fulfilling the preservation aspect of its mission. By making the archaeological collection more accessible to staff and researchers, they also have made presenting the results of our archaeological investigations easier as well. Archaeological artifacts are exhibited to the public at all MSHP sites providing a tangible connection to the lives of the people who lived and worked at the sites in the past.
From the Collection: Artifacts of Literacy Posted February 3, 2023 One of the next major projects for Mackinac State Historic Parks will be the reconstruction of a unit on the Southwest Rowhouse. To prepare, MSHP staff have been going over the archaeological records and artifacts from the 1960s, when the unit was originally excavated. Today we’re taking a look at various artifacts of literacy, including pencils and a pen knife. Curator of Archaeology Dr. Lynn Evans takes us through this peek at the collection.
Archaeology at Fort Mackinac – Provision Storehouse Posted January 27, 2023 The “Store House” is the structure labeled “I” on the west end of the fort on this drawing from 1796. Credit: Historical Society of PennsylvaniaOne of the largest archaeological excavations to take place at Fort Mackinac was at the site of the original provision storehouse. This excavation was carried out during the summers of 1981-82 by University of South Florida field schools directed by Dr. Roger T. Grange Jr. These were part of the commemoration of the bicentennial of Fort Mackinac. Dr. Grange’s final report was published as Number 12 in the Mackinac State Historic Parks’ Archaeological Completion Report Series (Excavations at Fort Mackinac, 1980-1982: The Provision Storehouse – Mackinac State Historic Parks | Mackinac State Historic Parks (mackinacparks.com) and was the basis of this blog post. The provision storehouse is an unusual structure because is has been excavated twice, in two different locations. It was originally built by British soldiers just inside the water gate at Michilimackinac (on the south side of the straits) in 1773. Being a relatively new building, it was moved to Mackinac Island when the garrison was relocated in 1781 and appears on early maps of Fort Mackinac. The mainland site was excavated in 1959 and the storehouse reconstructed in 1961. Today it houses the orientation film at Colonial Michilimackinac.Scissors from the early American occupation.Leather shoe parts from post War of 1812 deposit. On the island, the structure served as a storehouse through the first British occupation (1780-1796), the first American occupation (1796-1812) and the second British occupation (1812-1815). After the War of 1812, it was converted into a barracks, with workspace for military tailors and shoemakers, and a hospital. Its use as a hospital (1815-1827) overlapped with the service of Fort Mackinac’s most famous post surgeon, Dr. William Beaumont. A portion of the storehouse appears as a log structure next to the 1827 hospital painted by Mary Nexsen Thompson shortly before it burned down days before completion.Microscope lens, possibly used by Dr. Beaumont.Mary Nexsen Thompson painting of 1827 hospital with portion of storehouse. Credit: William L. Clements Library, University of Michigan A completely new hospital building was constructed in 1828, over the middle of the storehouse/1827 hospital, but oriented north-south instead of northeast-southwest like the original. A portion of the west end of the provision storehouse behind the 1828 hospital was the area of the archaeological excavation. No remnants of the provision storehouse are visible today, but you can stand on the original location while touring Fort Mackinac (opens May 4, 2023). You can also visit the reconstruction of the original provision storehouse at Colonial Michilimackinac (opens May 10, 2023) and learn more about Dr. Beaumont’s work at the American Fur Co. Store & Dr. Beaumont Museum in downtown Mackinac Island (opens June 3, 2023).
2022 Archaeology Field Season Wrap-Up Posted September 9, 2022 Possible milk pan.Potential sugar bowl. The second half of the 2022 Michilimackinac archaeology field season was as interesting as the first half, with several complementary finds. We found three more rim sherds in the southeast cellar which matched the large piece of bowl (more info here) found the first week of the season. From these, we can see that the vessel had a spout and may have been a milk pan used to cool milk fresh from the cow and allow the cream to separate. The southeast cellar also contained three pieces of what appears to be a sugar bowl, a large fragment of a saucer and several pieces of an unknown vessel with the handle broken off.Large fragment of a saucer.Unknown vessel with handle broken. Buttplate from a trade gun. The southeast cellar also yielded part of a buttplate from a trade gun. It does not match the buttplate finial found earlier in the season. It is thicker and engraved with a different motif. Brass scale weight. The central cellar yielded a second brass scale weight. It was in the form of a cup, from a nested set of weights. It weighed half of an apothecary dram and is stamped with what appears to be a fleur-de-lis. Joined sleeve buttonsEarring fragment. Following the single sleeve button found in June, a linked pair of sleeve buttons and an earring fragment were found in August. All had green paste stones, and all were found in the 1781 demolition rubble layer. Padlock The final unusual find of the season was a small padlock found in the southeast cellar [image 20220818_padlock]. It was only 1.75” tall. This fits in well with the image we have constructed of a wealthy household, as you do not need a lock unless you have something to protect. The site is now lined with plastic and packed with hay bales for the winter. Work has shifted to the lab, where the artifacts will be cleaned, sorted, counted, and identified over the coming months.
Mid-Season Archaeology Update Posted July 22, 2022 One-ounce brass weightFolded barrel band in front of remnant of a cellar wall post The first half of the 2022 Michilimackinac archaeological field season has been very productive. The southeast cellar continues to yield interesting artifacts, including a one-ounce brass weight from a balance-type scale. It is stamped with “GR” under a crown for King George. Two possible posts from the east wall of the cellar have been exposed. A folded iron barrel band was found adjacent to one of the posts. Several interesting artifacts have come from the central cellar as well. These have included part of a porcelain teacup, a lead seal, a plain brass button, and a brass band with iron rivets, possibly from a storage container. The squares on the newly-opened north row are all in or very near the 1781 demolition rubble layer. As in other areas of this house, a variety of ceramic sherds and ornate personal adornment items have been recovered. The adornment items include a green paste sleeve button and a shoe buckle fragment. The finial from the buttplate of a French trade gun was a more unusual find. A few artifacts possibly related to Anishnaabek presence have been found as well. These include several pieces of a stone smoking pipe bowl and a fragment of carved antler.This sleeve button would have functioned much like a cufflink today.This buckle fragment is probably from a shoe. The long side is 1.75” long.Finial from the buttplate of a French trade gun
Re-opening the Archaeological Site at Michilimackinac Posted June 10, 2022 The House E site with all of the squares open.Map of British features of House D showing House E cellar (F.866) to west of common wall separating Houses D & E.Late May saw the beginning of the 64th archaeological field season at Michilimackinac. We are continuing to excavate the rowhouse unit we have been working on since 2007. We have opened three new squares where we expect to find remains of the trench for the north wall of the house. This should be as wide as the excavation for this project expands. The house walls do not fall exactly in line with the grid. Because of this, when we excavated the rowhouse unit to the east (House D) in the 1990s, we excavated about a foot of the current house (House E) as well. In doing so, we uncovered the edge of the root cellar in the southeast corner of House E. We reached the bottom of the western two-thirds of this cellar at the end of last season. Now we have uncovered the eastern third, which we had protected and re-buried when we backfilled House D in 1997. Our first exciting find of the season came from the east section of the cellar, most of a redware bowl with a green-glazed border. We had found a matching rim sherd in the western edge of the cellar in 2018. The dark crescent-shaped area is the cellar. The rocky sand is the beach underlying the fort.Bowl with rim fragment from 2018 held in place.
The Untold Story of the Mill Creek Quarry Posted May 20, 2022 Originally established by Robert Campbell about 1790, the sawmill, gristmill and farming activities at Mill Creek remained active for about half a century. Known as Private Claim #334, the site was bought by wealthy Mackinac Island merchant Michael Dousman in 1819. Sawmill operations ran until about 1839, and after Dousman died in 1854, his heirs sold the property for just $400. When the township was resurveyed in 1856, updated maps showed no trace of buildings on Campbell’s original 640-acre claim. Local lore states that William Myers removed gristmill stones from the abandoned site about 1860 to use at his mills near Cheboygan.Lime Kiln ruins on Mackinac Island, 1917 About 1864, a new resource was tapped for the first time along the rocky bluffs of Mill Creek – limestone. People have quarried and processed limestone at the Straits of Mackinac since the construction of Fort Mackinac from 1779-1781. For many years, the old lime kiln on Mackinac Island was a tourist destination, and Lime Kiln Trail can still be enjoyed by visitors today. By the summer of 1827, a kiln was also in operation near the northwest shore of nearby Bois Blanc Island. Limestone in Michigan was formed millions of years ago, being composed of sediments at the bottom of ancient salty seas, filled with billions of fragments of corals and shelled creatures. Limestone is high in calcium carbonate, and when burned in a kiln, crushed, or pulverized, is valuable for making cement, concrete, mortar, and many other uses. Larger pieces of quarried stone were used to make roads, the stone walls of Fort Mackinac, its blockhouses, and officer’s stone quarters. Lime was first processed at Mill Creek about 1864 by a man with the last name of Young who stayed for a couple of years. The next record of limestone quarrying at the site can be found in a Cheboygan Democrat article, dated April 12, 1883. It reads, “Parties have begun to work preparatory to burning lime extensively at Mill Creek. They say that have orders for forty bushels per day during the season.” This record corresponds closely with the Michigan Central Railroad running tracks through the site in November 1881, making it easy to ship finished products to market. The first and only large quarrying operation at Mill Creek was operated by Willis G. Durrell, of Cincinnati, Ohio, from 1914-1923. Before organizing his company, Mr. Durrell began taking summer vacations in the vicinity of Burt Lake, Michigan. While there he learned of the Mill Creek site, which a local paper noted, “most of the county people know as a vast deposit of very pure lime rock, and which efforts have been made in the past to get capital to develop.” As his Cheboygan Limestone Products Company was being organized in 1913, an article in the Chicago publication Rock Products, detailed Mr. Durrell’s plans and described the site, noting, “It is known as the ‘Old Dausman tract.’” Mr. Durrell, assisted by his son Lawrence, was busy throughout 1914, hiring workers, purchasing and installing equipment, constructing kilns, and adding a railroad spur off the main line for easy hauling of finished products. Products included three grades of stone for road construction and “agricultural limestone” which was sold throughout lower Michigan.Rock bluffs at the Durrell/Mill Creek Quarry c.1915The November 13, 1914 issue of the Cheboygan Democrat described the growing operation as follows:Willis G. Durrell, 1856-1942“Mr. Durrell, president of the Cheboygan Limestone Products Co., located near Mackinaw City was in the city Monday and he informs the Democrat that they are installing at the plant new machinery for pulverizing limestone rock for agricultural purposes and as soon as it is in shape they will turn out two car loads of this product a day. It is taking the place of land plaster and vast quantities of it is new being used by farmers. It is especially needed in southern Michigan where they have vast tracts of sour lands and pulverized limestone is being used to bring the land value back… The pulverized limestone will be sold at the quarry at $1.25 per ton, which is reasonable, and already many farmers of this county are preparing to make a test of it on their lands. The company is also engaged in crushing rock for roads and other purposes. They have fifteen men at work now and will gradually increase their force.” To maximize production, Durrell purchased a Jeffrey Swing Hammer Pulverizer for use at the quarry. Installed in late 1914, this new technology crushed limestone to a fine powder, eliminating the need for burning lime in kilns. It also produced material for other uses such as top-dressing roads, fluxing stone for glass factories and steel plants, and concrete for cement walks. The Durrell, or Mill Creek Quarry, boasted an exceptionally pure product, being 98.71 percent calcium carbonate. Their advertisements in southern Michigan newspapers asked readers, “Why use low grade when pure stuff costs no more?” To verify its composition, 40 samples of Mill Creek limestone were taken in 1915 and examined by scientists at nine laboratories, including the Michigan Geological Survey, University of Michigan, and Emery Institute of Cincinnati.Advertisements from various Michigan newspapers, 1914-1915 Eclipsed by larger operations at Afton (near Indian River) and Rogers City, the Mill Creek Quarry ended operations after the 1923 season. From the 1930s through the 1950s, the abandoned quarry pits were featured stops for students to examine limestone strata during field excursions of the Michigan Academy of Science Arts and Letters and the Michigan Basin Geological Society. During this time, the greater portion of Private Claim #334 reverted to State ownership and was incorporated into the Hardwood State Forest, under the jurisdiction of the Department of Natural Resources. Located near today’s grassy picnic area, west of the mill pond, the old quarry pits were filled in before Historic Mill Creek Discovery Park opened in 1984. Archaeologists speculate that footings of the original sawmill may have been obliterated by quarry operations along the stream bed. The fact that other historic remains, including footings of the dam itself, were not destroyed is a fortunate footnote of history. Today, only a pile of rocky rubble remains along the Mill Pond Trail as evidence of a once thriving operation which remains an important part of the Mill Creek story.
Archaeology at Fort Mackinac – Three Blacksmith Shops Posted March 25, 2022 The third blacksmith shop is the building on the front left of the photo.One of the “missing” buildings at Fort Mackinac is the blacksmith shop. Military records, maps, and even a photograph indicate that a series of three blacksmith shops was present just inside the north sally port for most of the fort’s military service. An archaeological project to search for their remains was undertaken as part of the centennial celebration of the Mackinac Island State Park Commission in 1995 and the bicentennial of the arrival of American troops in 1996. The excavations were carried out as University of South Florida [USF] field schools under the direction of Dr. Roger T. Grange, Jr. Ford Motor Company sponsored the project. Information for this post was drawn from Dr. Grange’s unpublished reports and Sheila Stewart’s USF master’s thesis on the third blacksmith shop. Although the services of a blacksmith would have been required during the construction of Fort Mackinac, the location of his shop is not known. Based on the dates and nationalities of the military buttons excavated during this project, it appears that the first shop near the sally port was built by the Americans in the late 1790s. The remains of the first shop, especially the forge base, were preserved well enough to determine the basic layout of the shop. In addition to making and repairing tools and hardware for the construction and maintenance of fort buildings, and keeping arms in good repair, the blacksmith would have provided services to the Indian Department. The services of a blacksmith were commonly included in treaties with Native American nations.USF field school students excavate around the stone foundation of the second blacksmith shop. By 1828 the blacksmith shop was in poor condition, so it was dismantled and rebuilt in approximately the same location. Of the three shops, the second had the most substantial foundation, stone walls which are preserved below the fort’s sod today. The second blacksmith shop was destroyed by a major fire, which started in the nearby bakehouse, in 1858. The clearing of the fire rubble removed most of the artifacts and features from this era. Almost immediately after the fire, a third blacksmith shop was built in the same area. It sat on cornerstones, two of which survived, and its dimensions were partially determined archaeologically by the dripline in the gravel indicating the roofline. By analyzing artifact distribution and soil chemistry, Stewart was able to determine the shop layout, including the forge area, anvil mold, work area, and coal and metal storage areas. The artifacts from the third shop also reflect how the role of the blacksmith changed with the Industrial Revolution. By the 1870s the U.S. Army was using mass-produced weapons with interchangeable parts, so gun repair was no longer a major component of a military smith’s work. Hand-forged tools and hardware were replaced by cast iron and steel. Across the continent, not just in military garrisons, farrier work (shoeing horses) became the main task of blacksmiths. In 1875, this change led to a new blacksmith shop being built near the fort stables, which were located in what is now Marquette Park. The shop in the fort was used for storage for a few years but was dismantled by 1879.Although this “spread eagle with shield” button design was used from 1854-1902, its back mark of HORSTMANN BROS & CO/PHILA dates it to 1859-1863, within the date range of the third shop.] Today there are no visible remains of the blacksmith shops within the walls of Fort Mackinac, but the stone foundations lie below the grass just outside the barracks restrooms. Stop and imagine the sights, sounds, and smells of the blacksmith the next time you visit. Fort Mackinac opens for the season on May 3, 2022.
