This giant pile of rocks lies close to an outlook called The Pinnacle along the Appalachian Trail, and is an example of a “cairn,” albeit gone overboard. Stacking stones into towers has served as a direction marker, memorial, or spiritual commemoration across many world cultures. The term cairn is Gaelic, and means “a heap of […]

This illustration is the best I can do to represent American scientist Eunice Foote, since no extant images of her remain. This is a shame, because Foote was the first scientist to analyze the composition of gasses to predict what we now call the Greenhouse Effect. In 1856, hundreds of scientists were in attendance at

In the far north-eastern part of China, the beautiful but deeply inhospitable Flaming Mountains lie. Travellers going across the Silk Road in ancient history avoided this area, skirting south to parts of the desert that contained waterholes and vegetation. The Turpan Oasis was one of these (see second photo), and it was in this region

Although this photo doesn’t do the view justice, it does show the railroad tracks (if you squint, in the lower right foreground) that made the portmanteau village of Pen Mar possible. Now a virtual ghost town straddling the Pennsylvania and Maryland border and adjacent to the Appalachian Trail, Pen Mar got its start in 1877

On a lovely January morning, I walked the LeTorte trail, which runs along the eponymous nature preserve. LeTorte’s name comes from an early 18th-century French-Swiss explorer who built cabins in the area after receiving the land from William Penn. James and his wife Ann fought with the American Indians (probably Shawnee) in 1720, but

Today while hiking, my friend Erin and I happily encountered a group of folks doing trail maintainace as part of the Potomac Appalachian Trail Club.

A Roman (1st or 2nd c CE) and 12th-century examples of foliage faces that became known as “the Green Man.” For centuries, these carvings existed, adorning buildings, as a man’s face surrounded by leaves, or spewing greenery, or having hair that morphed into plants. But it wasn’t until folklorist Lady Raglan wrote an article that

Scientists are enabling us to save lives and hopefully prevent disaster in this COVID-19 pandemic — and coming up with big solutions to health problems is one of the main reasons their profession is so valuable. But for me there is another equally praiseworthy aspect: their contributions to unveiling the forces that shape our universe.
