Inside of Grant County in the state of Oregon you will find Seneca. This city is just 23 miles south of Canyon City and is right inside of the Blue Mountains. It rests along the perimeter of the Malheur National Forest. The town established a post office in 1895 and boasted a female postmaster by the name of Minni Southworth. Her brother in law was the popular Judge Seneca Smith which is how she was able to obtain the job. People began to move into this valley near the end of the 1800's but it wasn't until 1929 that the town began to grow. This growth was prompted by the construction of the Oregon and Northwestern Railroad, which is no longer in service. During that time, the Edward Hines Lumbar Company set up a railroad ship and planning mill for the town, making it an unofficial company town. The population reached 275 residents by the 1940's, but when logging declines the Hines company stopped running the lumber mills and the railroad. The city was incorporated in 1970 and the Hines Company ceased activity in 1984. The area spans 0.80 square miles today and enjoys 95 households and 60 residents living in the vicinity. Today, the main industries in the region consist of timber production and cattle ranching. There is one school in town and one post office.
