Confluence Project

The Confluence Project is a series of outdoor installations and interpretive artworks located in public parks along the Columbia River and its tributaries in the U.S. states of Washington and Oregon.

[1] The project draws on the region's history, including Native American traditional stories and entries from the Lewis and Clark Expedition journals, to "evoke a landscape and a way of life submerged in time and memory.

Lin collaborated with landscape architects, such as Johnpaul Jones, to produce earthen works that helped restore natural environments.

Each artwork was based on traditions grounded in Native American cultures and drew text from Lewis and Clark's journals.

The mission is to connect people to the history, living cultures, and ecology of the Columbia River system through Indigenous voices.
