“miles of abandoned weapons bunkers”

"Miles upon miles of rows of dirt-covered bunkers line the sides of Oregon’s I-82. The fields of camouflaged mounds dot the landscape in eerily perfect lines, but it's what these mounds once hid that's truly disturbing. Underneath these mounds are empty storage units that once housed everything from mustard gas to nerve agents like sarin.  The Oregon Umatilla Chemical Weapons Depot (UMCD) was established in 1941, with the mission of storing everything from blankets to ammo during WWII. That all changed in 1962, during the Cold War, when it became one of the world’s largest chemical weapons storage facilities. Just three decades later the depot began preparing for its closure, when in 1993 the UN passed a resolution that banned the storage and use of WMD’s that included blister and nerve agents. This required all the ammo and supplies to be shipped elsewhere and took about 20 years to complete. As one of nine US Army depots, the UMCD housed weapons including GB, VX nerve agents, and HD blister agent. The entire stockpile was disposed of by October 2011, “using high temperature incineration technology.” Now, the United States Army has successfully disposed of over “80% of the nation’s original, chemical weapons.” So, should you find yourself along I-82, keep an eye peeled as you pass by miles of dirt mounds. You’re actually cruising past bunkers that once housed 12% of America’s chemical weapons stockpile. Take a moment to pull over, if it’s safe of course, and see the view from the junction." -Roadtrippers The Umatilla Chemical Depot, (UMCD) based in Umatilla, Oregon, was a U.S. Army installation in the United States that stored chemical weapons. The chemical weapons originally stored at the depot consisted of various munitions and ton containers containing GB and VX nerve agents and HD blister agent. All munitions have been safely destroyed by 2011 and base closure operation are expected to be completed by 2015.

Only viewable while driving on I-84... if you navigate there, it leads you to a National Guard Training base, which I assume by the guards posted at the gate, you'd need a military ID to access.

See it from the road. I liked learning the history of these strange mounds along the road. I wouldn't make a special trip to see them though.
