Cascade Falls

Genevieve Wall of Nature Forward led a pleasant hike in Patapsco State Park, focused on Cascade Falls, a small waterfall in a creek that feeds the Patapsco River.

This 3+ mile hike was a bit more rugged than Nature Forward’s usual local forays, with a bit of rock scramble and several stream crossings. It was well scouted by Genevieve, so I had my stick and my good boots.

The woods are dominated by American Beech; we talked about two pathogens of this species, causing Beech Bark Disease (BBD) and Beech Leaf Disease (BLD). BBD was a new one on me, as it has not yet been reported in Fairfax County; however, it has been gradually spreading south.

The forb layer in this tract, unfortunately, shows a lot of Wavyleaf Basketgrass, today in abundant seed.

a little splashAt the falls, I believe that I spotted Snakewort (Conocephalum salebrosum) clinging to the damp rocks.

Maybe Happy Ending

Aronson and Park’s sweet rom-com of two washed-up “helperbots” with a slightly ambiguous twist at its conclusion features engaging leads and a listenable, if unchallenging, score. But the big winners in this production are the design team behind set, costumes, video, lights, and sound: Dane Laffrey, Clint Ramos, Ben Stanton, Peter Hylenski, and George Reeve. The clash of olive and pink on Claire and teal blue and earth tones on Oliver is quite tasty. Wagons silently smooch into place behind panels, drops, and scrims; dazzling projections recreate memories stored in the bots’ hard drives;1 and was that a hologram? The futuro-retro mail delivery chute is also a nice touch.

Granted, as the two bots set out on the journey that binds them together, the music picks up a crunchier tone, as in “The Rainy Day We Met.”

My wrapup reports for the Wood Duck and Hooded Merganser nesting season are sliding into the fall:

This report can’t be late, because it’s still hockey season, eh? Here’s our season totals.

Our Wood Ducks started fewer clutches than 2025 (11 vs. 8) and lost 3 of them (2 to predation, 1 to the unexplained death of the hen). 91 eggs laid, 52 hatched and fledged, 57% estimated fledging success.

Our Hooded Mergansers started one fewer clutch than last year (3 vs. 4). 28 eggs laid, 27 eggs hatched and fledged, 96% estimated fledging success.

It’s a typical pattern year-to-year that the HOMEs start fewer clutches but achieve better fledging success on a percentage basis.

Of the 16 boxes, 10 were used. We had a double clutch in one of the boxes. Our latest fledge date was 24 June.

Shenandoah National Park getaway 2026

I escaped the to-do list monster for two and a half days with a trip to Shenandoah National Park. I made four hikes; not too much of the flora and fauna was unusual, but a couple of the hikes themselves proved surprising.

I found resprouts of American Chestnut (Castanea dentata) in several places, none of them more than two meters tall. Eastern Comma (Polygonia comma) butterflies were the most common lep found, perhaps the most common insect found, including a scattering of them collecting minerals on a gravel verge. The most common bird I detected was probably Common Raven, which was heard quarking and flapping overhead at every site.

Following my much-loved copy of Circuit Hikes in Shenandoah National Park,1 the loop to Byrd’s Nest #4 came in a little lower than the guidebook read: 420ft elevation change, 520ft vertical ascent.2 Late purple asters are blooming in the park. I’m calling this observation Symphyotrichum phlogifolium. I found an interesting fly, ID not confirmed, and a new sharpshooter for me, Paraulacizes irrorata.

The next day, I started out with a loop around Blackrock, a hike that I also took in 2018. I added a side trip to the Blackrock Hut, which added time and altitude to the trip. I more or less knew what to expect on the last leg, but the steady straight-line climb on the Trayfoot Mountain Trail was relentless. A smol lycophyte, too tiny to get a solid ID; katydids chatting in full daylight; nice Virginia Jumpseed. An Oak Treehopper (Platycotis vittata) thought about hitching a ride with me at the parking lot.

After lunch at the Loft Mountain Wayside,3 I started up the Frazier Discovery Trail, which is marked as the Deadening Nature Trail on my map from 1988. I should have looked at the contour lines on the topo side of the map, because what I discovered is that even “nature trails” in the Park can be rocky, rugged, and vertical. This trail turned out to be the birdiest one of the trip, with a Barred Owl calling in the distance. Lots of spicebush in fruit.

last marker post for the tripFor my final walk, I picked another new trail just from looking at the map. A little tired from the previous three hikes in the previous days, I promised myself that when I was ready to stop climbing, I could turn around and descend. I settled on the Meadow Spring Trail: found no meadow (succession, man) but I found a spring and the ruins of a farmhouse. I made it to the end of the trail, where it connects to the Appalachian Trail, again climbing more than I expected. While there wasn’t much in bloom on the way up, there was a patch of asters for sweat bees to nectar on at the AT junction.

This time I stayed in the main lodge building at Big Meadows. Good location, lovely view, the restaurant ran out of fruit, managing the radiator made me feel like I was in a New York apartment in the 1940s.

Hike stats (all of these taken at naturalist/old man pace):

  • Byrd’s Nest #4, 2.7 miles, 2:40, 420ft altitude difference, 580ft vertical ascent
  • Blackrock-Trayfoot, 2.7 miles (est), 3:00, 580ft vertical ascent
  • Frazier Discovery, 1.3 miles, 1:50, 450ft altitude difference, 440ft vertical ascent
  • Meadow Spring, 1.4 miles, 1:50, 510ft altitude difference and vertical ascent

Pipeline

David Owen, “To Have and to Hold:”

[Fulfillment centers] are easy to spot from the air, because they’re immense, low, rectangular, flat-roofed, windowless, and, typically, clustered in industrial parks near airports and other transportation hubs. Self-storage facilities are almost always smaller, and they’re less likely to be encircled by eighteen-wheelers, but they’re similar in design and construction. Recently, it occurred to me that the ideal place to open a self-storage facility might be in the middle of one of those industrial parks, surrounded by fulfillment centers. That way, when you bought something from Amazon, it could be delivered directly to your storage unit, bypassing your cluttered home and sparing you the embarrassment of not remembering what you’d ordered the day before.

Intelligent design

… if we were created by God and granted wisdom, then perhaps we are still unfinished drafts. At times, one might even be tempted to say: If this is a divine creation, could God please stop joking around and take the blueprint a little more seriously?

Alexandria NABA Butterfly Count 2026

I returned to Huntley Meadows Park for the 2026 NABA count. After a slowish start, we found butterflies in pretty good numbers. About half a dozen Cloudless Sulphurs (Phoebis sennae). Even better were the lepidopteran larvae, including a dozen or so Common Buckeye (Junonia coenia), Smeared Dagger (Acronicta oblinita), and Spotted Apatelodes Moth (Apatelodes torrefacta)—a new one for me. Also, two lookalikes: Ancistrocerus campestris, a mason wasp, and Transverse-banded Flower Fly (Eristalis transversa).

But nary an Ocola Skipper to be found.

greening upIt’s the off season for ducks in nest boxes at Huntley Meadows Park: a good time to write a little about the boxes themselves.

box and guardno TyphaAs P. and K. are demonstrating here, a typical box for us is made of nominal one-inch wood panels, about the height but not the width of a dorm refrigerator, with a slightly sloping roof, and entrance/exit hole, and a door on the side. Each box has a painted number: the numbering system is there is no system. Sometimes a box is numbered (randomly) by the carpenter who made it, sometimes a box retains its number when it’s moved to a completely different place in the park.

nest box mount: back panel resting on PVC pipeA box is mounted on a metal pole, usually in some depth of water. And usually we sheathe the pole in a PVC sleeve, as a predator deterrent. As a second deterrent, we’ve attached a metal cone to the PVC sleeve. As you can see from the detailed photo, there’s still a bit of a gap between the apex of the cone and the sleeve: I conjecture that black ratsnakes can slip through the gap, so we’ve recently filled in with foam crack filler.

If you’re mounting boxes on square wooden posts, you wouldn’t have this gaposis problem.

nest box mount with U-bolt (shaft)nest box mount with U-bolt (thread)The box is attached to the pole in a couple of different ways. Typically, we drill two pairs of holes in the back of the box and pass through a pair of U-bolts, securing them with nuts on the inside. There’s not quite enough friction to hold the box in place, so it rests on the top of the PVC sleeve.

nest box mount with carriage bolt (thread)nest box mount with carriage bolt (head)I’ve also recorded at least one box that uses carriage bolts that thread through the box and the pole.

nest box mount with strapAnd a box with metal straps.

hasp and quick linkhook-and-eyeThe door must also be secured against predation. Whereas ratsnakes like to come in through the entrance hole, raccoons prefer finding a way to open the door. So we often close the door with a hasp and quick link, or with a hook and eye on a spring.

patchedThe inside of the box is fitted with a section of hardware cloth (wire mesh), which gives the ducklings more of a purchase when they’re ready to scramble out of the box. This element tends to be a point of failure as the box is used, so we might have to staple the mesh back in place.

roof patchside panel patchA typical box lasts about five to seven years in the field before it falls apart. If a box develops a knot hole that pops open, we can keep the box going for another season or two with a bit of plywood and some (clumsy) nailing.

Big beautiful

Adam said, “Our great and secret fear is that America may turn out to be a phenomenon, rather than a civilization. Hence, in part, the scale, the insistence, the need to prove the great mysteries obsolete or serviceable. We want our lust to be loved and called beautiful. To receive the homage due to love.”

Letters of recommendation: 1

Whenever I check into a motel, one of the first things I seek out is the literature display rack. I’ve grabbed info on antique malls,1 directions to the Goo Goo Shop in Nashville, opening hours for the Tinkertown Museum in Albuquerque (I need to go back in season)—I don’t always find something interesting, but once in a while I find a peach, like the brochure for The Dennos Museum Center in Traverse City, Mich.

very metaSo how did those racks and all those brochures get there? Well, at least for here in the mid-Atlantic, I may have found the source. In a brilliantly meta moment, I picked up a rack card for TDS Brochure Distributors. (They’ve allowed their domain to lapse, so it’s possible that they’re no longer operating under that name.)

From the back of TDS’s card:

Embark on a journey of exploration in our captivating region! Pick up one of the brochures, rack cards, maps, or visitor guides displayed here, and let it whisk you away to an unexpected and thoroughly delightful experience. Consider extending your stay to uncover the full spectrum of exciting attractions in the area. Your getaway to unforgettable moments starts with a choice from this display!

1Since my house is full, I really need to stay out of these places.

One more from Ratner’s Star (1976):

On the way home they sat in the next-to-last car. A tripping device failed to work and their train, braking late, ran into the rear of a stalled work train. Billy found himself on the floor of the car. Ahead was stunned metal, a buckled frame for bodies intersecting in thick smoke. Then there was a moment of superlunar calm. In this interval, just before he started crying, he realized there is at least one prime between a given number and its double. (p. 5)

What seven-year-old Billy has rediscovered is a variant of Bertrand’s Postulate.

Outgoing

How to Payformerly AddfareWord is that Metro’s venerable, perplexing farecard machines are soon to be replaced. So here’s maybe a last look at the old machines at my local station.

The farecard machines have been retrofitted more than a couple of times. Originally, they accepted only cash and dispensed a paper farecard.1 Now, credit/debit cards are accepted and what comes out is a laminated plastic stored value card.

Since there’s a rush hour premium added to the distance-based fare, it’s very easy to have insufficient funds on your card in order to exit (especially back in the old paper farecard days). (See the busy table of fares at the top of the machine.) Hence, the Exitfare machine, in original orange livery, which was designed to one purpose: top up your card so that you can exit. Fun fact: Exitfare was originally called Addfare, but riders would try to use it to add more than necessary to exit.
