Rocky Mountain Arsenal, Former munitions plant in Commerce City, United States.
The Rocky Mountain Arsenal is a former weapons manufacturing facility near Denver that now contains expansive lakes, grasslands, and forest areas. The property encompasses diverse habitats that support varied plant and animal communities across its grounds.
The facility was built in 1942 to manufacture weapons during World War II. After closure in 1985, the site underwent environmental cleanup and was transformed into a wildlife refuge.
The place stands as a symbol of environmental restoration and shows how communities transform industrial sites into green spaces. Today, visitors witness how nature reclaims the landscape and creates new habitats where few expected them to flourish.
The site is accessible by car, with driving routes available for wildlife viewing. Plan your visit during daylight hours and dress for changing weather, as the open landscape offers little shelter.
The property is home to a bison herd that has grown significantly since animals were first released there. These large herbivores now roam freely across the grasslands as part of the restoration effort.
