Centennial is a census-designated place (CDP) in Albany County
, United States
. The population was 191 at the 2000 census. On the west side of Centennial Ridge a copper claim was discovered by Jacob Schnitzler in 1896. As the Union Pacific Railroad was pushing west to link up with the Central Pacific Railroad, as part of the First Transcontinental Railroad, they sent logging crews into the Snowy Range
, in the Medicine Bow
Mountains, to cut down timber (mainly Lodgepole Pine) for railroad ties. A work camp was built on the site of the town. After they had completed most of their work and the workers started having conflicts with area Indians, the crews left the area. After the area was opened to homesteaders a few ranchers returned to the area.
