A cinder cone is a steep conical hill of tephra (volcanic debris) that accumulates around and downwind from a volcanic vent.The therefore mentioned Cinder Cone is located in a Valley Near the Columbia River Gorge in Skamania Washington.

The WIPP problem, and what it means for defense nuclear waste disposal
▻http://thebulletin.org/wipp-problem-and-what-it-means-defense-nuclear-waste-disposal7002

“It’s a surprise when there are no surprises," a cleanup worker told me a few years ago at the Hanford site in Washington state, once the world’s largest producer of plutonium for nuclear weapons and now home to a massive effort to stop leaking nuclear waste tanks from poisoning the Columbia River. This maxim can hold painfully true for a variety of events assigned an extremely small chance of happening. On February 4, 2014, assumptions of very low probability crumbled at the Energy Department’s Waste Isolation Pilot Plant (WIPP) near Carlsbad, New Mexico, when a fire in a large salt truck raged for hours, deep underground.

Ten days later, an even more unlikely accident happened: Wastes containing plutonium blew through the WIPP ventilation system, traveling 2,150 feet to the surface, contaminating at least 17 workers, and spreading small amounts of radioactive material into the environment.
