For 'Both Sides of the River', Kosmologym turned Dirtball into Watershold, a boat inspired by the historic gundalows that moved materials down the Shenandoah River before becoming materials themselves. Watershold turns the forms used to cast Dirtball’s concrete key into a gundalow. The gundalow is pulled apart by time on the Shenandoah river and washed ashore. The segments of the boat each hold fragments of Dirtball and the river.
