The Logan County portion of Cashion is part of the Oklahoma City Metropolitan Statistical Area.

[5] Cashion began as the town of Downs, Oklahoma on a hill 3 miles (5 km) south of the Cimarron River.

[6] In 1900, the Guthrie and Kingfisher Railway (later part of the Rock Island Railroad), which was building east from Kingfisher, and the Guthrie and Western Railway (an affiliate of the Santa Fe Railroad), which was building west from Seward, agreed to connect at a point a half-mile south of Downs.

[7][8] The site was on land owned by the Guthrie & Kingfisher Improvement Company, which sold lots, with the area becoming the town of Cashion.

[9] Roy, a graduate of the Hennessy Class of 1897, had a strong passion and belief in the freedom of the Cuban people.

On July 1, 1898, Cashion was killed by a gunshot to the head in the famous charge on San Juan Hill in Cuba.

At this time, two railroads were running two trains a day into town from both Guthrie (the Santa Fe) and Kingfisher (the Rock Island).

[9] A resurgent economy created more jobs in nearby Guthrie and Kingfisher, causing new residents to move into Cashion.

[11] In August of 2020, Cashion made national news after a police officer, Charlie Missinne, tasered a 65 year old woman after a traffic stop for a broken car light.

[9] According to the United States Census Bureau, Cashion has a total area of 1.7 square miles (4.4 km2), of which 1.9 acres (7,576 m2), or 0.17%, are water.
