I wrote about three very extreme places in the United States for a special series on PopSci.com.
These were a lot of fun to work on and write, and a great team of people helped with research, graphics and video. Find links to all three stories here:
Lucky Strike-Asteroids and Meteor Crater, arguably the best-preserved impact crater on the planet.
Town On Fire– Coal, and the story of Centralia, Pennsylvania, the town that’s been burning for decades.
Our Fault-Earthquakes and the San Andreas fault, one of the most dangerous systems in the world.
