Benchmarks: September 6, 1869: Pennsylvania's Avondale coal mine fire kills 110, igniting reform

In the mid-19th century, American industry was fueled by coal, which was provided largely by the anthracite coal mines of eastern Pennsylvania. The work drew tens of thousands of immigrants, including experienced English and Welsh miners, and many fleeing the Irish Potato Famine. But the work was dangerous, and each year thousands of workers died in the mines and many thousands more were seriously injured.

Isotopes suggest ancient turquoise mine was prolific

Few minerals are more iconic in the Desert Southwest than turquoise. The blue-green gemstone, which offers a stark contrast to the dusty red southwestern deserts, has been coveted for thousands of years by indigenous peoples, conquering Spaniards and now by a growing market around the world. Despite its past and present cultural significance, especially among indigenous populations, little is known about the early history of turquoise mining. Researchers have now uncovered previously unknown details about a historic turquoise mining site in Arizona that suggest it was more prolific than once thought.

Congress mulls options for abandoned mines legislation

Amid the well-publicized discussions over healthcare, tax reform, the federal budget and disaster aid in summer and fall 2017, a quieter conversation over mining legislation reform was also going on in Congress.

Down to Earth With: Deep-sea biologist Stace Beaulieu

People often find their way to the geosciences after a college class sparks their interest. But not Stace Beaulieu, a senior research specialist at Woods Hole Oceanographic Institution (WHOI) in Woods Hole, Mass. — she knew what she wanted to do at age 6. Beaulieu grew up in Florida and spent her childhood snorkeling and reading science magazines with pictures of deep-sea creatures that tantalized her imagination and piqued her curiosity. “I had a one-track mind pretty much from elementary school through grad school — I never changed my mind. I was so excited about learning about what was deeper. I still am today.”

Bringing geoscience to bear on the problem of abandoned mines

With 3 million gallons of acidic, heavy-metal-laden water behind an earthen plug at high elevation, Colorado’s Gold King Mine was, literally, a situation just waiting to go downhill. The blowout last August shone a spotlight on the larger problem of abandoned mine lands. What role do geoscientists play in solving it?

A labyrinth of silver mines uncovered on the shores of the Aegean Sea

By the fifth and fourth centuries B.C., silver mines under the ancient Greek city of Thorikos, now known as Lavrio, were the most important mines in Greece. Recent underground exploration of the network of tunnels found at the foot of the city’s Mycenaean-aged Acropolis is shedding new light on the scale — and miserable conditions — of the mines.

Down to Earth With: Tectonicist Eldridge Moores

When Eldridge Moores was 10 years old, his family lived in Crown King, Ariz., a tiny, remote mining settlement high in the rugged Yavapai Mountains northwest of Phoenix. Money was tight and his family rarely traveled, so Moores vividly remembers a holiday road trip to visit his father’s relatives near San Francisco. The Bay Area left a deep impression on Moores, and, at the end of the journey, upon reaching the first of four switchbacks on the narrow dirt track that led up to Crown King, Moores vehemently pronounced that he would do everything he could to get out of there.
