The problem with the 49 Square Miles Project is that nobody checked to see if San Francisco is actually that big.
Here’s the answer from Wikipedia:
Now, did they include the Farallon Islands? Hell yes, plus tiny parts of the North Bay and the East Bay that we also have, through Accident of History:
“Several islands—Alcatraz,Treasure Island and the adjacent Yerba Buena Island, and a small portion of Alameda Island, Red Rock Island, and Angel Island are part of the city. Also included are the uninhabited Farallon Islands, 27 miles (43 km) offshore in the Pacific Ocean.”
So, having proved that, let’s fix the Chron’s graphic:
You know Chron, you could have rounded up to 47 and you could have even rounded up to 50, if your ardor for California’s Fourth-Largest City demanded it.
But you can’t round up to 49.
Wiki wins again.
