Colorado State Highway 12 as it passes through Segundo.
Segundo is a small unincorporated community in Las Animas County, Colorado, United States, west of Trinidad.
Segundo, Colorado, was a company town where the CF&I coal company housed its workers. It offered adequate housing and promoted upward mobility through its sponsorship of a YMCA Center, elementary school, and some small businesses, as well as a company store. However air pollution was a constant health threat; the houses lacked indoor plumbing. As demand for metallurgical coke declined, the mine laid off workers and Segundo's population declined. After a major fire in 1929, CF&I left town and Segundo became practically a ghost town.
