First of all, let’s play a game of identifying the northernmost, southernmost, westernmost, and easternmost points of San Francisco. If you guess, you’re going to make mistakes.
Hint: They’re all islands, some are mere “rocks.”
All right, in no particular order, here are the answers:
Seal Rock, aka Saddle Rock
North Farallon Islands
How’d you do? Check here.
Now, add up all the San Francisco County land area amidst these points and you’ll get 46.something square miles. Sry.
Anyway, this is wrong:
So that’s your answer, 46 square miles. Oh, you want to round up to 47? OK. No but really you want to round up to 49, you know, for the poetry of it all?
Well, then why not round up to 50, or 100 square miles then?
Of course, back in the day, 49 square miles was a fair guess – 7×7 right? But the problem with that is geography. We were forgetting the Great San Francisco Bight, the part of SF’s northwestern corner that just aint there.
These days, of course, we have the tools to be accurate.
