    Jack London: author and navigator
    From: Frank Reed

    Here is author Jack London aboard his vessel, the "Snark", probably in 1908 shooting the Sun with his sextant. Can we estimate the altitude of the Sun from the photo?

    I saw a copy of the second photo a few days ago in an exhibit of maritime photography at the little San Francisco Maritime Museum. It's a staged portrait showing Jack London and his wife Charmian studying a map of some sort, and obviously that's a sextant serving as a prop or a paperweight in front of them.
