Fog Navigation

This morning brought with it a nice thick radiation fog, which the sun will probably burn off soon. There is not forecast to be much wind today, but even a breeze deals with radiation fog, usually anything over 12 knots.

No visible sun, no discernible wind, these are the conditions that remind us that the trees reflect their environment over a long period. They act as a giant USB stick of data about thousands of days of sun and wind. All we need to do is tune our senses and look for it. The thin branch in the bottom left of the picture has been curved upwards by the prevailing southwest winds over time. using-trees-to-navigate
