What’s In the Mud?

During the June 2013 flooding of the High River region, the Museum of the Highwood’s archival collection was immersed in water for eleven days. After eleven days the archival collection was salvaged and moved into freezers for two years, prior to undergoing conservation treatment through the Flood Advisory Programme. The items underwent conservation treatment, which was performed by Emily Turgeon-Brunet, Lisa Isley, and Jayme Vallieres. The archival collection had been covered in frost, mud, and mould and required cleaning, stabilization, and rehousing.

Since the entire region of High River had been underwater, it left a lot of questions about what exactly the conservators had been cleaning off of the archival collection. What was in the mud?

A sample of High River mud that was removed from the flood damaged collection material was sent to Emeritus Professor of Chemistry, Dr. Herbert Gus Shurvell, at Queen’s University Department of Art Conservation to undergo FTIR and XRF testing.

FTIR:

Fourier Transform Infrared Spectroscopy is most commonly used to collect information on surface properties and functional groups present in organic and polymeric substances. Dr. Shurvell provided a spectrum that compares the mud sample and the references natural sienna and terra cotta.

XRF:

X-Ray Fluorescence Analysis is used to collect information on the elemental composition, and provide the relative concentration of elements in comparison to one another.

Results:

The FTIR spectra showed peaks typical for the presence of silica-alumina clays. The XRF results showed the strong presence of iron and calcium, with addition to silicon, potassium, titanium, manganese, zinc, rubidium, strontium, and zirconium. Some of these are toxic when encountered at high concentrations, though they are all found naturally in rocks and soil. Radioactive isotopes of some these elements are found naturally in nature, while others are the byproducts of industrial processes.

Salvage at a Glance

Since September 2014, the Flood Advisory Programme’s Lead Team has been working with our institutional members on salvage and recovery from the June 2013 floods. We had the opportunity to treat records from the Museum of the Highwood, which was devastated by the flood. The Lead Team transported the frozen photographic material to the Provincial Archives of Alberta’s conservation lab to treat the records and to begin reconciling the records with their descriptions. Here are a few photographs of this process:

We are continuing to work with Museum of the Highwood to salvage their archival records and make their collection accessible again. We would like to thank the Museum of the Highwood for allowing us to share these photographs, Yesan Ham for taking the photographs and the Provincial Archives of Alberta for providing us with the lab space to treat the records.
