Following a night of heavy rain, an interpreter leading a guided hike on the Fossil Discovery Trail on the morning of Friday, July 2nd, noticed an object sliding out of a crevice in a cliff along the trail. Interpreters could also see a similar object further back in the crevice. One of them identified the objects as possible dynamite and a protection ranger was called. The Fossil Discovery Trail was closed and barricaded and the Quarry construction site, about 100 yards away, was shut down. ATF responded from Salt Lake City and confirmed that the two objects were dynamite sticks, manufactured in September of 1921. During their investigation, they located two more sticks partially buried in the crevice. It’s likely this dynamite was being used by Earl Douglas and the Carnegie Museum for excavations in the 1920s. Bomb technicians removed the dynamite sticks and detonated them at a gravel turnaround. The trail was reopened in time for Saturday morning tours.
