Tracey and myself constantly ponder the extent of subterranean facilities operated by the U.S. military and U.S. government. A great way to put the capabilities of underground construction into perspective it to see actual undergrounds facilities. Let’s take a look at a few available videos that realistically show underground tunnels and cave systems inside the United States.

Springfield, MO caves & Terminal

In a video posted online by YouTube Channel Chad Rich the public gets a first-hand look at a massive tunnel system in Springfield, Missouri. This video is extremely interesting. At one point near the deepest point inside, a strange white wall with a red door can be seen built into the cave wall.

It’s incredible to think about what extent the U.S. military would be able to construct massive, if not, city-size underground systems throughout the United States.


Kansas City, Missouri “SubTropolis”

Welcome to the “largest underground system in Kansas City. Missouri” says the YouTube Channel Kip and Jake. In this video that the two truck drivers / adventurers take the public through a massive tunnel cave system where business commerce is actively in operation. But what else is happening inside? With a tunnel system so hidden away from prying eyes it would seem easy to hide black ops or black budget corporations.


Cheyenne Mountain, Colorado

Hidden 2,000 feet below Cheyenne Mountain in Colorado is rumored to be a city-sized military facility. Locals in the area tell stories of what may lie beneath the mountain and what the U.S. military is doing so deep under ground.

9NEWS in Colorado covered the secret underground base in a special broadcast on local TV.

Just south of Colorado Springs is one of the most famous military bases in the world, but you can’t see it. It sits one mile inside of the granite Cheyenne Mountain, 2,000 feet down from the surface. – 9NEWS special “Under Colorado”
