I was invited to conduct a Walkshop with Civic Studio in Grand Rapids, MI. I collaborated with studio members to design a Walkshop that was based off of previous Walkshops I had conducted and have a site specificity. Studio members decided to work off of a clay impressions format I had developed. They were dissatisfied with the source of clay being obscured and decided they could forage clay from the Grand River to use during the event. They also worked with a local power plant and obtained permission to have the clay brought to a low fire temperature after the impressions were made. This ‘firing’ would take place in the the city boilers when they flushed during their by-yearly cleaning. The public Walkshop started at Civic Studio and participants read a few short articles including sections of Perec’s Species of Spaces. Participants made maps that highlighted a particular sensory experience of the city. We then set out in the snow to find infrastructure to take clay impressions of. Studio members shared various historical research about the space as we walked.
