The Conservation of the Brother Jonathan Chest (2017)
Two hours into the voyage from Crescent City, California to Victoria, British Columbia in July 1865, Captain Samuel DeWolf ordered SS Brother Jonathan to set a return course. Eight miles outside of Crescent City, a wave smashed the vessel into a rock, sinking it in under an hour—along with most of the cargo and passengers. It wasn’t until the 1990s that the wreckage was rediscovered; in May 2016, a shipping crate salvaged from the wreck was sent to Texas A&M University’s Conservation Research...

Conservation of Waterlogged Textiles from CSS Georgia (2017)
During recovery of material from CSS Georgia, numerous textile artifacts were recovered and transported to Texas A&M University’s Conservation Research Laboratory for treatment. Unlike terrestrial locations, waterlogged sites like CSS Georgia provide a stable environment of constant temperatures, low sunlight, and minimal exposure to micro-organisms, allowing for preservation of organic material normally lost to taphonomic factors. With maritime Civil War sites like USS Monitor and H.L. Hunley...
The Conservation of Wooden Hoops from Emanuel Point II (2018)
During the excavation of Emanuel Point II, a 16th-century Spanish ship that sailed as part of colonization fleet led by Don Tristán de Luna y Arellano, a large number of wooden barrel hoop fragments were recovered. These vary in size from a few centimeters to almost 20 centimeters in length and were found both loose and bound together. Once removed from the site these artifacts must be conserved using the best practices available. The conservation laboratory at UWF has elected to use a freeze...

Considering the Possibilities of an 'Urban Public Archaeology': The Findings of a 60-Year Retrospective of Public Archaeology in the City of Philadelphia (2016)
In practice, and in scholarly debate, historical archaeologists pursue urban archaeology either as the archaeology ‘of cities’ or as archaeology that is done ‘in cities’. Likewise, in practice and scholarly debate, there is variation and divergence in the definitions and terminologies related to what 'Public Archaeology' is and what it does. Drawing on the dynamic, diverse, innovative, and usually long history of public outreach and engagement in the city of Philadelphia, this talk -- part of a...
Constructed Differences And An Archaeology of Material Practices in Antebellum Communities of Color (2018)
Slavery and the Atlantic economy created mixed Native/African communities in southeastern Massachusetts, a reality which widened after the Revolution. Historical archaeologists can deepen our understandings of the differences and interactions amongst such communities. As color lines became more rigid in such places, their inhabitants often made common cause. Yet the ancestral differences amongst them also lead to the emergence of groups of "coloured foreigners" on Indian reservations, mostly...
Constructing A Community Of Color: A Spatial Analysis Of New Guinea On Nantucket (2018)
In 1827, the community of New Guinea on Nantucket, MA opened the doors of the African Meeting House. The African Meeting House’s construction was a milestone event in the establishment of this thriving community of color. People of African and Native ancestry on Nantucket coupled this with buying property, building homes, starting businesses, and founding institutions to create a space that allowed them refuge from daily experiences of racism, and facilitated community resistance. By examining...

Constructing Heritage for the Historic U-Lazy-S Ranch (2017)
Heritage as a cultural process is observed through three-layers: people, history, and landscapes. These layers are analyzed together to gain a holistic view of heritage construction at the historic U-Lazy-S Ranch located along the eastern edge of the Llano Estacado in northwestern Texas. This generational cattle ranch has been in operation for over 100 years. As ranching requires large tracts of land spread across the landscape, multiple sites must be examined and combined with documentary...

This is an abstract from the "Exploring the Recent Past" session, at the 2019 annual meeting of the Society for Historical Archaeology. In an increasingly mobile world, the places most central to peoples' identities are often modern and fluid, as opposed to fixed and related to historic origins. This paper discusses 1947 Partition refugee resettlement housing in Delhi which was an important site of national identity construction. Following Indian independence, the millions of refugees who...
Constructing Privileged Landscapes In 19th Century Southern New England (2016)
Alix W. Stanley spent the early 20th century purchasing old family properties in the ‘Stanley Quarter’ section of New Britain, Connecticut. The properties, owned by Stanley family members from 1644 through the mid-18th century, provided his ancestors the ability to generate considerable wealth, some of which Alix’s father used to create the Stanley Tool and Die Company. In 1928, Stanley gifted the 360 acre patchwork, which included his mansion and historic Stanley family homes to the city for...
Constructing Technology in the Mining Workplace: Gold Mining in Depression-Era Fairbanks, Alaska (2015)
Industrial landscapes can present a rather impersonal perspective due to their immense scale and emphasis upon technical processes. Anthropological perspectives on technology nevertheless emphasize that all technological systems are socially constructed, drawing attention to the political and cultural considerations behind decision-making. This paper utilizes a sociotechnical systems approach to investigate depression-era gold mining near Fairbanks, Alaska. Attention is given to the...
Constructing the Borderzone: The Role of Positional Warfare and Natural Border Ideology on a 17th Century French Colonial Landscape (2018)
The majority of archaeological interpretations of French involvement in North America have not accounted for underlying European social constructs and ideologies. As archaeological investigations of the French In North America move away from recognized strongholds and expands through the greater French Atlantic World, a critical examination of the archaeological record through these constructs is vital. This paper examines one episode of 17th century expansionism along the Lake Champlain...
Constructing the Community: A Multi-Scalar Analysis of Runaway Slave Identity in 19th-Century Kenya (2018)
Like Maroons elsewhere in the world, runaway slaves in Kenya were thrown together by circumstance and carried diverse social experiences and cultural practices with them into freedom. Given this heterogeneity, archaeologists have grown increasingly interested in the mechanisms by which Maroons created communities of broader cultural coherence. This paper explores the creation of two communities by self-emancipated people in 19th-century Kenya, Koromio and Makoroboi. Here, I use an expanding...
