Number 10 in the Critical Spatial Practice series. Project and text by Nina Valerie Kolowratnik. Edited by Nikolaus Hirsch and Markus Miessen. Featuring images by Trevor Paglen. "In The Language of Secret Proof, Nina Valerie Kolowratnik challenges the conditions under which Indigenous rights to protect and regain traditional lands are currently negotiated in United States legal frameworks. The tenth volume in the Critical Spatial Practice series responds to the urgent need for alternative modes of evidentiary production by introducing an innovative system of architectural drawing and notation." --publisher's statement.
