The story
Sumpter boomed on gold in the Blue Mountains of eastern Oregon. Platted in 1898 and reached by the narrow-gauge Sumpter Valley Railway the year before, it grew fast to several thousand people, with brick business blocks, hotels, and a stock exchange — the self-styled Queen City of the mines.
A fire on August 13, 1917 tore through downtown and destroyed close to 100 buildings, and the mining economy was already fading; the town never rebuilt to its old size. A second act came in the 1930s, when a massive gold dredge began working the valley gravels along the Powder River, running from 1935 until 1954 and leaving miles of cobble tailings behind it.
About 200 people live in Sumpter now. The dredge is preserved as the Sumpter Valley Dredge State Heritage Area, and a restored stretch of the old railway runs excursion trains in summer, so the town survives as a small living place wrapped around its mining relics.
What remains today
The three-story Sumpter Valley gold dredge, the restored narrow-gauge railway and depot, brick ruins from the 1917 fire, and tailing piles along the valley.
