I’m pretty much obsessed with muons—subatomic particles that have been used to map the interiors of archaeological ruins—so I was interested to see that muons have now also been put to work mapping the bedrock beneath glaciers in the Swiss Alps. It is the “first application of the technique in glacial geology,” Eos reports. Even better, it uses underground railway infrastructure—the Jungfrau rail tunnel—as part of its experimental apparatus.

Robert Macfarlane has written a movie called Mountain, narrated by Willem Defoe. Macfarlane also recently joined Twitter, where he has rapidly accumulated nearly 28,000 followers.

The world’s sand is running out—indeed, “it’s scarcer than you think,” David Owen writes for The New Yorker. As highlighted on Twitter by @lowlowtide, the piece includes this great line: “The problems start when people begin to think of mutable landforms as permanent property.” Sand, and the peculiar economies that value it, has gotten quite a bit of attention over the past few years; among other coverage, a long feature in Wired two years ago is worth checking out.

Researchers at Penn State have figured out a way to generate electricity from the chemical mixing point where freshwater rivers reach the sea. “‘The goal of this technology is to generate electricity from where the rivers meet the ocean,’ said Christopher Gorski, assistant professor in environmental engineering at Penn State. ‘It’s based on the difference in the salt concentrations between the two water sources.’”

Hawaii is experiencing an unusually intense barrage of high tides, known as “king tides.” “For the people of Hawaii, alarm bells are ringing,” Adrienne LaFrance writes for The Atlantic. “King tides like this aren’t just a historic anomaly; they’re a sign of what’s to come… Scientists believe Hawaii could experience a sea-level increase of three feet by the year 2100, which is in line with global predictions of sea-level change and which would substantially reshape life on the Islands. That’s part of why scientists are enlisting volunteers to help photograph and describe incremental high tides across Hawaii.” Read more at The Atlantic.

Over at Places, landscape architect Zach Mortice takes a long look at what he calls “perpetual neglect” and the challenge of historic preservation in African-American burial grounds. Badly maintained—and, in some cases, almost entirely erased—black cemeteries reveal “that the racism and inequality that plague African Americans in life are perpetuated in death,” Mortice suggests. This is “nothing less than a preservation crisis for black burial grounds across the country.”

I recently discovered the existence of something called Betonamit. Betonamit is a “non-explosive cracking agent,” essentially a “non-toxic” powder that can be used for the slow-motion demolition of buildings and geological forms. “When mixed with water and poured into holes 1 1/4″, 1 3/8″ or 1 1/2″ diameter, it hardens and expands, exerting pressures of 12,000 psi. Reinforced concrete, boulders, and ledge[s] are fractured overnight with no noise, vibration, or flyrock.” I’m imagining a truck full of this stuff overturning on a crack-laden bridge somewhere, just an hour before a rainstorm begins, or a storage yard filled with crates of this stuff being ripped apart in the summer wind; a seemingly innocuous grey powder drifts out across an entire neighborhood for the next few hours, settling down into cracks on brick rooftops and stone facades, in sidewalks and roadbeds. Then the rains begin. The city crumbles. Weaponized demolition powder.

In any case, I actually stumbled upon Betonamit after reading a few blog posts on that company’s in-house blog. Atlas Preservation has a handful of interesting short articles up documenting their preservation work, including what might be the oldest gravestone in the United States and the challenges of open-air cemetery preservation. Let’s hope no one goes wandering amongst the tombs with a bucket of Betonamit…

The BBC went into horror-movie mode earlier this month, asking, “what would happen if we were suddenly exposed to deadly bacteria and viruses that have been absent for thousands of years, or that we have never met before? We may be about to find out. Climate change is melting permafrost soils that have been frozen for thousands of years, and as the soils melt they are releasing ancient viruses and bacteria that, having lain dormant, are springing back to life.” The headline is straight-forward enough, I suppose: “There are diseases hidden in ice, and they are waking up.”

Fans of John Carpenter’s (excellent) 1982 film The Thing might be interested to hear that the original score has been remastered and released on vinyl. The final product is visually gorgeous—and temporarily sold out. Keep your ears peeled for further pressings.

A retired F.B.I. investigator has newly dedicated himself to tracking down lost apple varietals of the Pacific Northwest. They are not extinct; they have simply disappeared into the background, both ecologically and historically. They are trees that have “faded into woods, or were absorbed by parks or other public lands,” but the apples that grow from them can still be enjoyed and cultivated.

If you are interested in apples and their history, meanwhile, don’t miss the late Roger Deakin’s superb book, Wildwood: A Journey Through Trees.

Blending into the natural landscape is the subject of a fascinating piece over at Public Domain Review about the early wildlife photographers, Richard and Cherry Kearton. In order not to scare away their subject matter, the Keartons constructed artificial trees, put on short, deliberately misleading performative displays for wildlife, and carved masks that would help camouflage them against the woodlands.

There’s more—always more!—to link to and read, but I’ll leave it at that. For other, ongoing links, I am also on Twitter.

The Doomway

[Image: The beginning of the Broomway path, at Wakering Stairs].

One of my favorite chapters in Robert Macfarlane’s recent book, The Old Ways: A Journey On Foot, has been excerpted over at the BBC—and, although the excerpt itself is well worth reading in full, it only reminds me of how good the entire chapter really is (note, as well, that the following quotations come from Macfarlane’s book, not from the BBC excerpt, lest there be variations in text).

The chapter documents a hike along the Broomway, an eerie coastal path across tidally exposed sands out where the Thames meets the North Sea.

The satellite photo, above, shows the Broomway’s launching point, at a place called Wakering Stairs. From there it heads into a shifting marine landscape of tidal flats—a “vast revealed world,” in Macfarlane’s words, of mud, half-buried guideposts, and omnipresent quicksand.

The path is also known as the Doomway: it is a path that leads “straight out to sea.”

The Broomway is “allegedly ‘the deadliest’ path in Britain,” Macfarlane writes, “and certainly the unearthliest path I have ever walked.”

It only exists at low tide, for starters, and it can often be followed only with the visual help of unstable wooden poles driven into the ground to mark its route across the landscape. Its unusual name, in fact, comes from “the 400 or so ‘brooms’ that were formerly placed at intervals of between thirty and sixty yards on either side of the track, thereby indicating the safe passage on the hard sand that lay between them.”

Without those brooms, the path—and not just where it’s heading, but the route you’ve already walked to get there–would disappear from view entirely, in effect stranding you at sea.

That might sound easy enough to account for, if you have a good sense of direction. “When the tide comes back in, though,” Macfarlane warns, “it comes fast—galloping over the sands quicker than a human can run.”

A sense of how difficult the Broomway can be to follow is revealed by Macfarlane’s description of how people used to walk it in bad weather. “Until hand-held compasses became available to walkers, the safest way of navigating in bad conditions, when it was impossible to see from broom to broom, was with stone and thread. Walkers carried a 200-foot length of linen thread, with one end tied to a small stone. They would place the stone next to a broom and then walk away in what they believed to be the right direction, unspooling the thread as they went, until they could see the next broom.”

They would then either haul the stone up to their current position and start the process all over again, or they would search back through the mist and darkness for the correct route forward.

The path “is thought to have killed more than a hundred people over the centuries,” and what an utterly lost and disoriented death it must have been.

If you’re tempted to hike it—as am I—please take the necessary precautions; consider reading Macfarlane’s book the first necessary step.

(On a side note, it is very much not the same thing, but Andrew Michael Hurley’s novel The Loney takes place in a coastal British landscape that has its own disappearing footpath across the tidal sands; it can be, at times, uneven, but it is a good read for any fellow fans of Gothic horror).
