The natural Navigation: The Right Course, Naturally

Just came across this incredible video. I don’t think it’s new, but well worth watching if you’re interested in just what our senses are capable of. Inspiring.

This morning was filled with a breezy walk up to Halnaker Windmill. The sun was out for most of the way up the hill, but the sky also had a generous share of cumulus clouds.

Natural navigation is a mixture of art and science and this can be felt very strongly when the sun disappears behind the clouds. Science allows us to understand the direction that the sun will be and there is an art to reading the cloud edges to reveal the direction of the sun, even when we cannot see it.

The low trees on the exposed hilltop had been groomed by the prevailing southwesterly winds. There were green, grey and gold lichens layering the various sides of the brick.

This isn’t about the Force, although I did read recently that a lot of Scottish policemen have put ‘Jedi’ down as their religion on their work forms.

More days than not I spot an example of the sun influencing nature in a way that is new to me in some way. In general terms it is fairly old news that a place that receives no direct sunlight will appear different in some way. It is in the detail that the novelty is to be found. The more obvious signs might be that it has different plants growing and an abundance of mosses and lichens.

The more fascinating signs are subtler, created by factors that are minute but combine to create an effect. The first picture shows how broadbrush nature can be. Despite looking in one direction towards a single hillside, as many as six different bands of colour are visible.…

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.

A Lancaster uses the moon to navigate at Goodwood Revival last weekend. Maybe not, but nice shot by Ben Davis.
