The natural Navigation: The Right Course, Naturally

It’s 8.15am this morning out on the Downs and this sheep’s shadow tells us that we are looking south. Her wool, or ’sheep fur’ as some would have it, is blowing from the same direction as the sun and gave me a constant reference all morning.

On a completely unrelated note, there is an article about the RGS in today’s Telegraph that I have somehow appeared in.

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.

The second picture…

Possibly the worst blog post title that I have yet come up with, and there have been a few…

Our cat, Murphy, can be seen reflecting the direction of the last of the suns rays here.

The tree shadows in the distance have broken free from the woodland in the background too for the first time this year at sunset.

In the spirit of randomness to which this posting has succumbed I thought you might like this puzzle, set by a friend and former NN alumni.

Do not be alarmed if my postings continue to be sporadic, poorly constructed, lacking in theme, good titles, concise argument or beautiful short sentences. Most of that energy is being directed into the book at the moment.

I’ve been experimenting over the past few nights, as we approached the full moon, with a technique that I’ve been working on that combines two others. It is possible to find direction using the moon in a number of ways: by its shadow, by using a tangent to its crescent and by understanding its phase relationship with the sun.

A very indirect method, that I have not come across anywhere else before, is to use moonlight reflected off cloud edges to reveal the direction of the moon, then to use an understanding of its phase to determine direction. Like a lot of methods for finding your way using the moon, it sounds a lot more complicated than it actually is, but it does still come with some inbuilt errors. I will try to persevere and experiment with this method some more over the coming months and let you know how…

In this photo you can see the dew that the sun has not yet burnt off. The shadow itself is mostly moving right to left in this picture, leaving the thin band of wet wood in the shade all the time. This thin band is a rough east-west line at all times of the year, but quite an accurate one at times like this, close to the spring and autumnal equinoxes.

The small patch of moisture that is in the sun reveals the direction that the shadow is shortening, a crude north-south line as we near the middle of the day.
