Tamastslikt Cultural Institute
Client: The Confederated Tribes of the Umatilla Indian Reservation

Completion Date: Summer 1998

The Tamastslikt Cultural Institute is the final interpretive center of four that commemorates the 150-year anniversary of the Oregon Trail. Located a few miles east of Pendleton, Oregon on Interstate 84, the Tamastslikt Cultural Institute includes indoor exhibit areas, research facilities, and storage areas for tribal members' personal artifacts. It also includes an outdoor Living History Village with interpretation of the tribes' traditional lifestyles.
Landscape Sections
The original concept for the landscape design was centered around the tribes' traditional use of fire in the landscape, a virtually unexplored area of plateau tribal culture. McCormack Landscape Architecture designed a one-mile entrance road that meandered through the site to maximize the views of the Blue Mountains to the east. This loop road was to be planted with native plants that resemble pre-settlement plant communities of fire dependent pine forests typical in the Northwest. The plant palette included sagebrush, native grasses, and forbs.

As visitors approached the parking area and the interpretive institute the landscape was intended to represent higher elevation forest communities, including large stands of ponderosa pine and several species of native woodland shrubs. Due to budgetary constraints, much of the landscape planting was never installed, but MLA's original site master plan was implemented.
