Scattered throughout the rolling grasslands of America are many historic forgotten sites from the Cold War. ICBM development during 50s and 60s was quick with breakneck iterations of designs so these launch facilities were often obsolete by the time they were completed and put into service.
Here is a 3D Radiance capture of some structural WWII remains found at the Rocky Mountain Arsenal Wildlife Refuge. The site was used during the war years to create chemical weapons and continued into the Cold-War until nuclear weapons became the US primary deterrence. Searching for peacetime operations the facility manufactured fuel for NASA and leased some of it’s property to Shell Chemical Company for the production of agricultural chemicals. Eventually the site was demilitarized, cleaned up and turned into a wildlife refuge.
It’s a picturesque location close to Denver they did a great job in restoring how it may have looked prior to the installation. it’s easy to see some bison/buffalo if you are visiting Denver and are looking to do so.
Somewhere north of Cheyenne Wyoming monolithic remains of the Cold War still stand.
In Los Alamos New Mexico you can find this memorial of Dr. Oppenheimer & Gen. Groves. It’s about a block away from Oppenheimer’s Manhattan Project home. The whole block is maintained by the National Parks Service as a National Historical Park.
I have a strong interest in our atomic history and Cold War so I have visited Los Alamos many times through the years. The Oppenheimer movie has noticeably made the mesa and surrounding area more popular.
