Lit glass and cedar installation which acts as a memorial/monument to the Columbia and Fraser/Thompson Rivers. This work deals with the issue of dams and the health of river systems. It contrasts the history of the Columbia which has been dammed 14 times on its main line and the Fraser/Thompson which has never been dammed on its main line. It memorializes the flooding of Celilo Falls, the “oldest continuously inhabited community on the North American continent until 1957, when it was submerged by the construction of the Dalles Dam” on the Columbia River.
