Long Pond Trail Vistas in Maryland

You are looking at vistas along the Long Pond Trail, an isolated and somewhat arduous trek through some of the loveliest mountainous paths that make up the Green Ridge State Forest in western Maryland.

Here is a handsome example of a Brood X cicada, after emerging from its hole underground (second photo) of seventeen years. These “periodical cicadas” are the insects that spend the longest amount of time developing from egg to adult. And their history is fascinating.The European settlers who came to North America were reminded of locusts

Virginia First Landing

Virginia’s First Landing State Park

For some reason I thought Virginia’s First Landing State Park evoked a _The Pirates of the Caribbean_ vibe. With its dense canopy of bald Cyprus trees emerging from the swamps, the forest’s beauty was accompanied with the sounds of frogs, birds, and cicadas.First Landing, like so many other spots of preserved forest in this country,

Virginia Wildlife Conservation

Virginia’s Back Bay National Wildlife Refuge

A lovely chapter in human history was undertaken with the formation and development of south-eastern Virginia’s Back Bay Natinal Wildlife Refuge. Formed in 1938 to provide a safe migration zone for migratory bird species, the Back Bay NWR was doubled in size to include over 9,000 acres in the 1980’s as the Virginia Beach area

Roman Farming

Ancient Roman Farming and Invasive Species

Where I live in south-central Pennsylvania, farmers and outdoor enthusiasts are well aware of new invasive species posing a threat to our forests and crops, like the Emerald ash borer and the Spotted lanternfly. It is easy to be lured into a myopic idea that the migration of fauna and flora mostly affects humans today

“I’m gonna have to science the shit out of this,” says the main character of Andy Weir’s _The Martian_, and proceeded.to use every bit of his resourcefulness to harness the power of knowledge to save himself. That movie is fictional, but actual scientists have done this (Hello, COVID-19 vaccination developers, I’m talkin’ to you there).

Fowler’s State Park and the Works Progress Administration

Fowler’s State Park is another example of the good work done to heal clearcut land and create wild spaces during the Great Depression. Located in south-central Pennsylvania, it is a 104-acre state park now, but was leveled in the first decade of the 20th century by a lumber company. Thanks to the Works Progress Administration,

Ohiopyle of the Youghiogheny River

These are the white-capped rapids of the Youghiogheny River in the Pennsylvania State Park called “Ohiopyle.” One of the guides from our rafting trip there this weekend said the name came from a time when folks from the flat-land state of Ohio drove their cars too fast down one of the many mountainous roads and

Waterfall

Hocking Hills Ohio Region

The Hocking Hills region of south-eastern Ohio is a jewel of an area — ravines, caves, and stone walls interweave throughout old-growth forest. Water is everywhere: streams, small cataracts, and waterfalls echo in many parts of the forest.The area was formed millions of years ago, when the Appalachian Mountains were eroding and the shallow seas

Leaf

Hocking Hills State Park

Hocking Hills State Park in Ohio has long been a place of interest for human cultures. The Blackhand sandstone formed a series of ravines there, and coupled with the abundant water supply allowed for a micro-climate atypical for Ohio. This explains the existence of trees like black birch, Canadian yew, and hemlocks which don’t normally

These watercolor images are mock-ups by

“Green Elf Cup” Fungus on Appalachian Trail

This is a close-up picture that I took earlier this month near the Appalachian Trail in Central Pennsylvania of a very tiny fungus with an adorable moniker and a long pedigree for human use. Called “green elfcup” or “green wood cup,” the technical name of this mushroom is “Chloriciboria aeruginascens,” and although it is a
