The story

How Sumpter came to be

From Wikipedia’s history of Sumpter.

Read it all →

The community was platted in 1889, and became a mining boom town about 10 years later. Until transportation by rail became feasible in the area, Sumpter was little more than "a huddle of crude log cabins."

A narrow-gauge railway reached Sumpter in 1897. Built by David C. Eccles, the Sumpter Valley Railway (SVRy) ran 80 miles (130 km) from Baker City through Sumpter and on to Prairie City, which it reached in 1907. Until the line shut down in the 1930s, ranchers, mining interests, and timber companies used it to move freight.
