Kosoma is a ghost town and former railroad station in Pushmataha County, Oklahoma, United States. It is located just off Oklahoma State Highway 2, about 10 miles (16 km) north of Antlers.


Kosoma is located in a rugged but scenic area. It is adjacent to the Kiamichi River at the base of Big Mountain, also known as Deer Mountain. Close by is Lost Mountain, notable for its relative cone shape and location in the middle of the Kiamichi River valley, apart from other mountains. The area of the valley floor on which Kosoma was built is bracketed by two locally prominent and well-watered streams: Buck Creek to the south and Pine Creek to the north. A permanent settlement has existed at the site of modern Kosoma since at least the 1880s. During the 1880s, the St. Louis-San Francisco Railway, more popularly known as the “Frisco”, built a line from north to south through the Choctaw Nation, connecting Fort Smith, Arkansas with Paris, Texas. The railroad paralleled the Kiamichi River throughout much of its route in present-day Pushmataha County. Train stations were established every few miles to aid in opening up the land and, more particularly, to serve as the locations of section houses. Supervisors for their respective miles of track lived in the section houses to administer the track and its right-of-way. These stations also served as points at which the trains could draw water.





Current Status:

At this writing, Kosoma is a ghost town with only two or three buildings still standing. These are found just off the short “Kosoma Loop” off State Highway 2 and have been subject to vandalism and theft by visitors, and neglect by current owners of the property. During World War II, the Kosoma area was the site of two lethal air crashes. British pilots operating from a Royal Air Force base in Texas, hampered by poor weather, crashed into White Rock Mountain and Big Mountain, killing four crewmen. Two planes were destroyed, while a third plane crash-landed successfully a few miles northwest at Jumbo. On February 20, 2000 the AT6 Monument was dedicated in the fliers’ honor at the crash site on Big Mountain, just southeast of Kosoma. Over 1,000 people attended the ceremony, and the story was carried by the British Broadcasting Corporation and many newspapers around the world.


A United States Post Office was established at Kosoma, Indian Territory on November 28, 1888, a testament to its early vitality so soon after the railroad opened. With the logging of forests in the region, Kosoma went into a steep decline during the early 1900s (decade), culminating in the loss of its post office in 1954. More information on Kosoma and the Kiamichi River valley may be found in the Pushmataha County Historical Society.
