On April 6, an Airman from the Mountain Home Air Force based was walking his dog on the Snake River when he found the artillery round over a cliff.
The Airman reported the device to the Elmore County Sheriff's Office. Bomb technicians say the device was a M107-155mm artillery round that contained 15 pounds of explosives and a live fuse, which was still in tact.
Bomb technicians told Elmore County that it's likely the artillery round has been in the desert for quite some time. Officials haven't used a device like that since the 1960s.
The device was determined to be too unstable and officials destroyed the device on site.
