I'm not sure where the rumor got started but I'm sure with the top-secret Hanford site during World War II being located here, rumors started swirling.

Here's Why A Secret Laboratory Might Exist Inside Rattlesnake Mountain

What makes the notion plausible is the fact that there was once a missile base located on the south-eastern side of the mountain. It was installed in 1943 but dismantled in 1958.

It makes perfect sense that when the government seized the land to appropriate it to Hanford for nuclear research, that they drilled into the side of the building for a secret laboratory.

Remember The Rattlesnake Mountain Observatory?

Another reason people would believe that a secret laboratory exists is that for several decades, the mountain had The Rattlesnake Mountain Observatory on its summit. The Observatory was installed on the land in 1966.

The telescope was once the largest permanently mounted telescope in Washington State. It was heavily used in the 1980s but soon became unused for several decades after that.

What Happened To The Rattlesnake Mountain Observatory?

The Rattlesnake Mountain Observatory was dismantled in 2008 due to the fact that the Department of Energy wanted to return the mountain to its natural state and conditions.

The Observatory was moved to the hills of Wallula, Washington so the telescope is still active and operational.

Have You Ever Taken The Reactor B Tour?

I've taken the Reactor B tour (a must tour) if you are fascinated by the history of Hanford and Michelle our tour guide informed us that there really isn't much mystery on what's on the Hanford site these days.
