Ephedra (technically Ephredra sinica) or ma-huang, is a shrub with small scaly leaves that comes from northeastern China, Russia, and Mongolia, and is especially interesting in the history of medicine. Recipes using ephredra have been used for thousands of years in Classical Chinese medicine. Frequently the plant has been a key ingredient in treating asthma […]

Winterthur is a jewel of an estate located in northern Delaware; it is the ancestral home of the du Pont family, one of the wealthiest in American history. Although its museum and library are famous for their collection of Americana, it was the gardens that Henry Francis du Pont most cared about on that property.

In my home state of Pennsylvania, now is the season of the Mountain Laurel blooms. This shrub (Latin name “Kalmia latifolia”) grows indigenously all along the eastern seaboard from southern Maine to northern Florida, and was used by Native Americans — the wood was good for carving into digging utensils, earning the plant the moniker
This is a mouflon, a type of mostly wild sheep that is a likely ancestor of all the domesticated sheep on earth today. Even if most of our clothing isn’t made of wool and most of our food isn’t lamb, human life wouldn’t be the same without this animal. Sheep and goats were the first

Today I got a chance to hike Old Rag Mountain in the Shenandoah National Park, and everything about it was phenomenal: yellow butterflies so heavy they wobbled in their paths, mountain laurel and tulip poplar in bloom, full streams feeding the spring life. The Old Rag Trail is most famous for the rock scrambles up
Yesterday, I was fortunate to experience the full solar eclipse from the Pymatuning State Park Reservoir in western Pennsylvania. The light turned silvery as the sun neared total obfuscation, and green colors emerged and reds dimmed, the effect of our eyes’ cones coming offline and employing the rods more. Shadows close to the ground sharpened
Pine Grove Furnace is at the top of the Blue Ridge Mountains near my home in south-central Pennsylvania, and is a beautiful wooded area that feels remote — as of this spring in 2024, it doesn’t even get cell phone reception — yet, it’s only a 20-minute drive from my suburban dwelling. In fact, there

We need to talk about pig farming in the Early Middle Ages. Pigs weren’t usually the most important domesticated animal for folks living in Western Europe between 500-1000 CE, but they shaped the lives of almost everyone. In a Michael Pollan “who’s-dominating-whom,” sort of vibe, historian Jamie Kreiner’s research demonstrates that although Medieval folks of

The Luray Caverns in northern Virginia are one of the most touristed cave systems in the world, drawing about a half a million people a year. They are adorned with striking rock formations of stalagmites, stalactites, and columns, all made from white calcium carbonate, red-toned iron oxide, and grey magnesium oxide. These permeate the limestone

One of the joys about cutting-edge studies that merge scientific data with the discipline of history is the chance to answer questions that we never thought we’d be able to. This photo of Greenland’s ice sheet gets at the way that climate scientists are trying to understand one of the most transformative aspects of earth

The Laurel Highlands Hiking Trail is a 70 mile stretch of forested lands begining in Ohiopyle and heading generally northeast almost to Johnstown. Begun in the 1970’s, it is an example of the invaluable natural patrimony of the state of Pennsylvania.
Just to the west of Las Cruces New Mexico, along the I10, is this ginormous statue of a roadrunner. It is built out of completely found materials — stuff like shoes, cell phones, old wire, crutches, headlights, and old toys. Artist Olin Calk created the recycled bird in 1993 to examine “consumption, recycling, and just

The Franklin Mountains have seen human activity since at least 12,000 years ago, but their name came from a much more recent source, when a rancher named Benjamin Franklin Coons settled in El Paso in 1849 — he was such a heavyweight in the region that locals used to call the city “Franklin” in the

These photos taken last weekend show vistas along the Loyalsocks Trail, one of the many stunning forested hiking pathways in Pennsylvania. Taking its name from the Loyalsock Creek (which translates from an American Indian name for “middle” creek), the Loyalsock trail is nearly sixty miles. The portions shown here include Sones Pond, which was built
Twenty-one years ago in 2001, the Burd Run Nature Trail and Restoration was established to reverse the damaging effects of an artificially straightened stream channel which had caused erosion and environmental degradation. (See second image). Shippensburg University (particularly the Geography and Earth Science Department), Shippensburg Township, the Cumberland County Conservation District, and the Conodoguinet Creek

An ancient bristlecone pine over 5,000 years old is the oldest living thing on earth (at least, as far as scientists could document in 2016). That means it was contemporary with the first urban civilization in Sumer! The tree grows in the White Mountains in California in the Inyo National Forest. The location of the

Big history post here (big history meaning all of history, not just human), about the fabulousness of how evolution works. This is about the ways bees created the colors we see on flowers. We know that bees are super-pollinators critical for much of earth’s plant life. And we observe how bees are drawn to sweet

The ruins of Suso Monastery in San Millán de la Cogolla look eerily beautiful in this image, evocative of a distant past whose details are lost to us now. Situated in northern Spain, they are some of the last surviving remains of the Visigothic Kingdom that ruled the Iberian peninsula from the late fifth century

Tonight Shippensburg University welcomed guest lecturer Wawa Gatheru, a leader in the contemporary U.S. environmental justice movement. She had many interesting things to say, but since I am an historian, I especially appreciated her discussion of how the legacy of American slavery has led to environmental inequity today. Wawa Gatheru pointed to two ways this

These are the views of Chimney Top, a Tuscarora quartzite outcropping at the end of the North Fork Trail on the similarly named mountain in West Virginia. Pictures don’t do this place justice – besides the immensity of scale that my photographic skills couldn’t capture, its beauty was enhanced by the wind and the solitude.
