It’s bonfire season here in the Fort Valley. I live in a forest, and that forest is full of dead and downed wood. Motivated by a desire to (a) reduce forest fire risk and (b) clear out some of the area under the trees for unobstructed recreation, I gather it up and periodically burn it … Read more
Not only does it turn out that peat grows on hill tops, not just valley bottoms, but it can slough off and create “peat slides” too!

I just finished this book, about the botanical and agricultural predilections of United States ‘founding fathers’ George Washington, Thomas Jefferson, John Adams, and James Madison. Three of these farmed and gardened in Virginia, one in Massachusetts. Some were federalists, others republicans who championed the rights of the states. Some were slave owners, others not.

What is Kenny pointing at here? Why, it’s a boulder. Where did it come from? Look uphill: This is as perfect an example of root wedging as I’ve seen! Spotted it last Friday along the C&O Canal towpath.
Here’s a little scene along Route 340 / 522, north of Front Royal and south of Double Tollgate, Virginia, in the Shenandoah Valley: The rock here is limestone and shale of the Edinburg Formation, a late Ordovician unit that records the transition from passive margin sedimentation to the increasingly ‘dirty’ clastic influence of the Taconian … Read more
Have a gander at this: Given that this is a Friday on Mountain Beltway, you might expect to see a fold here, and indeed, there’s something wavy and high-contrast running through the center of this sample. But that’s no fold. It’s a fossil plant! A “reed” of some kind, I guess. You can also see … Read more
