The Rivers of Steel National Heritage Area was created by Congress in 1996, to preserve, interpret and manage the historical, cultural and national resources dedicated to “Big Steel” and its related industries. The area encompasses eight Western Pennsylvania counties, including Washington, Allegheny, Greene, Fayette and Westmoreland. The program is multifaceted, and incorporates a museum in the historic Bost Building in Homestead. They also have a vast archive of historic photos and documents. We reached out to them for some images along the Monongahela River Valley. For more information, including a full list of programming and events, visit riversofsteel.com.
