The Aylmer, Colorado, post office opened on March 23, 1900.[1] On August 7, 1902, an explosion of dust ignited by giant powder at the Bowen Mine killed 13 people.[2] The precise location of the town site is unknown to the GNIS,[3] but newspaper articles reporting the 1902 Bowen Mine Explosion place the town "about a quarter of a mile below the mine",[4][5] near Trinidad.
The name of the Aylmer, Colorado, post office was changed to Bowen on September 18, 1906, and it remained in operation until January 15, 1929.[1] The community took the name of Thomas F. Bowen, the owner of the Bowen Mine and a state legislator.[6]
The 1911 Colorado Business Directory described the town as "Coal mining town and station", population 200, on the Colorado and Southern Railway.[7]
