Umapine, Oregon

Umapine is an unincorporated community in Umatilla County, Oregon in the Pacific Northwest region of the United States. Located near the city of Pendleton, Oregon, Umapine sits along local transportation routes and agricultural landscapes associated with the Blue Mountains (Oregon and Washington), the Umatilla River, and the Columbia River basin.

History

Umapine's settlement history intersects with the histories of the Walla Walla people, the Umatilla Indian Reservation, the Oregon Trail, and the Lewis and Clark Expedition era patterns of exploration.

The community developed alongside regional rail and road projects associated with the Oregon Railroad and Navigation Company and later the Union Pacific Railroad, while local agriculture grew in response to markets in Pendleton, Oregon, Hermiston, Oregon, and Boardman, Oregon. Political decisions at the county level by Umatilla County, Oregon officials and initiatives from the Oregon Legislature influenced public services, and Umapine residents have historically interacted with institutions such as the U.S. Postal Service and the Oregon Department of Transportation.
