Fossilized Past, attempted to understand the land and environmental racism around Lake Michigan, where I live now. This work results from 1.5 years of environmental research and surveys of the Great Lakes region with environmental engineers, Architects, Civil engineers, cultural critiques, and a whistle-blower examining and investigating the soil close to Oil pipelines and industries. The data extracted from the samples became the sonification basis of algorithms that produce tonalities from sound samples of the sites we have investigated. This iteration serves as a cartography of toxin-impacted regions, primarily on treaty lands and black, immigrant, and working-class neighborhoods of the urban areas of the Great Lakes.
