In seven stages, Cory Tamler spends the autumn walking the twenty-seven kilometers of the Panke River from its two tails in Bernau to its two mouths in Berlin. Some stages are walked with the public, others with smaller groups of companions. Many walks are designed with collaborators. Each walk considers the Panke as an interlocutor and experiments with performative, literary, and oral forms of encountering the river and recording the encounters.
