Hey, look, I’m the new Eastern Bureau at Bernalwood!

Bernalwood

If you live on Peralta Avenue in Bernal Heights, you’re probably used to getting phone calls from lost delivery drivers.  They’ve managed to find the 200 block, you’re in the 500 block; how many obstacles could there be between you?

Turns out, there are a lot. That staircase on the right is the 400 block of Peralta. But how did Peralta “Avenue” end up in no fewer than eight non-contiguous segments? In theory, it was supposed to be a (mostly) continuous street:

That’s a 1924 Rand McNally map, courtesy of David Rumsey. Peralta and Esmeralda are highlighted. These roads existed mostly on paper, as planned improvements. Note that “paper” Esmeralda runs right over the top of Bernal Hill: Sutrito Tower would be at the intersection of Esmeralda and Shotwell. Fourteen years later, these roads remained wisely unbuilt:

San Francisco Stadium, in 1938 Google Earth

Above: Jobius Technologies cutting-edge imagery combines historical aerial photographic mapping, Google Earth projections, and Bernalwood-brand-appropriate annotations. Future work is planned to incorporate time-lapse video and reverse-engineered La Lenguan animated GIF technology.

The amazing Harrison Ryker aerial map photos of 1938 San Francisco are now, thanks to the David Rumsey Map Collection, available as a layer in Google Earth! When I first saw these aerial photos at Burrito Justice, I was curious about the stadium on the upper right of this Google Earth view — a race track identified by Burrito Justice as San Francisco Stadium. I would have been able to see it from my apartment building, but alas, it wasn’t yet built when the track existed. Nevertheless, I decided to put my model of it in the scene above, since nobody was using the land. (I’d build a model of the stadium, but I’ve only ever seen the one photo of it, Ryker’s, looking straight down.)

Eric Fischer @enf found some references to the old San Francisco Stadium in Google Books:

Automotive industries: Volume 75, 1936

There are, of course, many well-organized midget racing speedways such as Madison Square Garden Bowl at New York, River View at Chicago, Walsh Stadium at St. Louis, San Francisco Stadium at San Francisco, Municipal Stadium a…

Fire engineering: Volume 90, 1937

Fog Nozzle Tested Fognozl Applicators, one of the several types of fog nozzles marked by the Fog Nozzle Company, Los Angeles, Cal., were given a test in the San Francisco Stadium. A sedan was doused inside and out with fifteen gallons of gasoline and set afire. The fire was extinguished in eighteen seconds with the use of a 10-foot duraluminum Fognozl Applicator, with a 1-inch Type B head. But eighteen gallons of water were used. Smoldering upholstery in the car was extinguished with a 5-gallon back pump, equipped with a 2-foot applicator

So that’s exciting. But it doesn’t seem that it lasted long. I found only one mention of it in a city directory, from 1936.

By 1945, the land it stood on was part of a Marine Corps Supply Depot (see 1947 map on last page of this report, PDF). Also from that report, tantalizing evidence of many more aerial photos of the area: “October 2, 1995, aerial photographs were reviewed for the years 1935,1938, 1948, 1955, 1961, 1966, 1968, 1969, 1972, 1975, 1981, 1991, and 1994.” “Aerial photographs dated 1935 through 1994 (Pacific Aerial Surveys, Oakland, CA).” Pacific Aerial Surveys is now part of HJW Geospatial. They charge royalties for distributing their imagery, so I probably won’t be able to post any here, but I’m going to try to get a look at them.

Moonrise: A Second Camera

The moon was full last night, and I lucked out on weather — as expected. It’s been a weird winter.

I added a second camera last night: my old iPhone 3GS, far left, propped up in the box that the Photojojo telephoto lens and tripod came in. It was listing to the left, but I propped it up with the little dinosaur toy Photojojo puts in all their shipments. (And I forgot to take a closeup of it. The shot above was taken with an iPad, an unweildy camera.)

I uploaded the raw videos, both wide-angle and telephoto to YouTube. But here’s how they look edited together, using iMovie on the new-ish Mac:
