Ephrata (e-fray-tuh), a pleasant small farm town and the Grant County seat, is in the exact center of Washington. It was settled quite early because its abundant natural springs made it an oasis in the dry steppe country of the Columbia Basin. Native Americans visited the springs, as did cattle drovers after American ranchers stocked the open range. Ephrata began to grow after the Great Northern Railroad established a terminal here in 1892. Cattlemen took advantage of the railroad to round up and ship out thousands of wild horses that roamed the range. The last great roundup was held in 1906, when the remaining 2,400 horses of a herd that once numbered some 25,000 were corralled and shipped off.
