Atlas Obscura has organized Obscura Day, to happen in cities worldwide on March 20. The idea seems to be explorations of strange places and collections of stuff, some usually closed to the public. Some of the fascinating ones: (I skew a bit towards the science-y…)
- Brooklyn: Join the Brooklyn Historic Railway Association for an exploration of Vanderbilt’s lost subway tunnel, right under Atlantic Avenue in Brooklyn. Rediscovered by an urban explorer in 1980, the tunnel remains one of New York’s great secrets.
- Bucks County, Pennsylvania: Bring hammers, mallets, bats, and other percussive instruments for this gathering at the mysterious Ringing Rocks Park in eastern Pennsylvania, where the stones have a most curious property: they ring out musical tones when struck.
- Hutchinson, Kansas: Sixty-five stories below Hutchinson, Kansas sits a massive salt mine with mineral veins stretching from Kansas all the way to New Mexico.
- Niagra Falls: Join us at the Niagara Science Museum for an afternoon of classic, historical experiments conducted with restored antique scientific equipment.
- Portland: Join us a tour of the world’s only nuclear reactor run by undergraduates. Learn about nuclear science, and experience the blue glow of Cherenkov radiation.
- Iceland: A special tour of the Icelandic Phallological Museum in Husavik.
- Tokyo: Michael John Grist will be leading an Obscura Day expedition to the G-Cans project. G-Cans is a massive underground waterway and water storage area built by the Japanese government to protect Tokyo from flooding during the monsoon seasons.
But out of all of those, the most promising to me is a local expedition to California City, put on in collaboration with BLDBLOG:

In the desert 100 miles northeast of Los Angeles is a suburb abandoned in advance of itself—the unfinished extension of a place called California City. McMansions can be made out here and there amidst the ghost-grid, mirages of suburbia in the middle of nowhere. Meaningless STOP signs stand guard over dead intersections.
And it’s a weird geography: two of the most prominent nearby landmarks include a prison and an automobile test-driving facility run by Honda. There is also a visually spectacular boron mine to the southeast—it’s the largest open-pit mine in California, according to the Center for Land Use Interpretation—and an Air Force base.
To make things more surreal, in an attempt to boost its economic fortunes, California City hired actor Erik Estrada, of CHiPs fame, to act as the town’s media spokesperson. The history of the town itself is of a failed Californian utopia—in fact, incredibly, if completed, it was intended to rival Los Angeles.
California City is now the site of a proposed mega-farm for solar energy harvesting, as well as for a bizarre plan to build the so-called Cannabis City of the Future.
Note, however, that this is not a guided tour; it is simply an organized simultaneity of people all going out to investigate these streets en masse. Armed with cameras, microphones, sketchbooks, GPS devices, quickly scrawled notes for future blog posts, and more, we’ll be exploring the site at our own pace, perhaps even miles apart at various times. This is not a guided tour with an expert on the area.
Locals, there are also San Mateo, SF and Palo Alto events. Dang, I’ll be travelling for my spring break water trip in the wee hours of the morning on that day, but this is a helluva vacation checklist for the nerd and nerdette who spent Valentine’s Day assembling an electronic arts project. Not that I’d know anything about that, heh heh. Go forth, kids – I will live the Obscura Day vicariously through you!
(Thanks, Greg!)
