“This was the worst manmade event ever, by far,” Wannier said. Together with researchers from Berkeley Lab and The University of California, Berkeley, Wannier was able to determine that these particles were created during the A-bomb hit, which leveled a 4-square mile area of land and destroyed and damaged about 90% of Hiroshima’s infrastructure. Image Credit: Anthropocene, Volume 25, March 2019 Particles collected from beach sands in Japan’s Motoujima Peninsula. Some Hiroshima particles had a rubber-like composition, and others were coated in silica or glass. However, Wannier noted that the particles found near Hiroshima were slightly different than those that were made during the K-Pg boundary. The Cretaceous-Tertiary (K-T) boundary is now referred to as the Cretaceous-Paleogene (K-Pg) boundary.Ī meteorite impact, such as the one that occurred during the K-Pg boundary, causes liquified ground material to launch into the air, which are formed into glassy droplets during the explosion. “They are generally aerodynamic, glassy, rounded - these particles immediately reminded me of some spherule (rounded) particles I had seen in sediment samples from the Cretaceous-Tertiary boundary,” Wannier continued, in reference to the mass-extinction event that killed off the dinosaurs 66 million years ago. “You couldn’t miss these extraneous particles.” “But there was something else…it’s so obvious when you look at the samples,” Wannier said of the glassy particles found in the sands of Japan’s Motoujina Peninsula, located near Hiroshima. “I had seen hundreds of beach samples from Southeast Asia, and I can immediately distinguish mineral grains from the particles created by animals or plants, so that’s very easy,” he said. His study of the particles, published in the journal Anthropocene, likens the particles to those left over from massive meteorite strikes. There are multiple no-trespassing signs.Career geologist Mario Wannier has identified tiny glass particles found in beach sands near Hiroshima, Japan as fallout debris from the atomic bomb that hit the city on August 6th, 1945. By doing so you risk bodily harm and/or prosecution for trespassing on private property. WARNING: Under no circumstances should you enter these properties. The film is eerie when you compare it to some of the historic photographs you see on old postcards for sale on eBay! Burke is just a few miles from the very historic Wallace, Idaho. Others have filmed through car windows as they drove through the ghost town. Over the last few years, several drone pilots have flown their drones over the town. Today, the town is abandoned, but the remains of a handful of buildings are still standing. Once home to the Hercules, Hecla, Star and Tiger mines, Burke’s final mining operations ceased in 1991. Because of labor disputes, there was also violence among the miners in town.Įventually, mining operations started to slow and people started leaving Burke. The town itself was plagued by avalanches, floods and fires, including the Great Fire of 1910. The hotel wasn’t the only part of town ransacked by a natural disaster. It was damaged in a fire and eventually torn down in 1954. Yes, the main street, railroad and a stream all ran through the lobby of the hotel. The architectural feat that Burke was best known for was the Tiger Hotel, a 150-room boarding house for miners, that had to straddle the railroad.
