The Bernalwood blog alerted us to this interesting photograph, sent out by Chris Hadfield, commander of the International Space Station over his Twitter feed. (Twitter is a social medium that allows people to share their pictures and their thoughts in 140 characters or less. Bernalwood is a fun and creative blog for the Bernal Heights neighborhood.)

While they were focused on the visibility of their neighborhood, and Commander Hadfield was looking at the Golden Gate Bridge, we of course looked for Sutro Forest. And there it is – visible from the International Space Station. (Twin Peaks is barely visible, but the greenery of the forest – that can be seen from space.)

How iconic is that?
