The natural Navigation: The Right Course, Naturally

My research into this subject constantly leads me, very willingly, back to the thin line that runs, curving between philosophy, religion, science and nature. If such a line exists – discuss!

I would go so far as to say my work would be very awkward if my personal jury had come in unanimously in favour of any hard views in any of those areas. Sometimes there is a deep longing to know more about things that I know I likely never will. It is hard to articulate this sensation perfectly, but it would perhaps be summed up well by saying that it can sometimes be assuaged by Frank Lloyd Wright’s line, ‘I believe in God, only I spell it Nature.’

There are some natural phenomenon that deeply spiritual people jump up and down about and then point to, in a calm spiritual manner, but which secularists wave away nonchalantly as ‘one of those…

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…

A walk in the woods yesterday revealed some natural and unnatural clues.

This primrose, the only one in the area, was unsurprisingly in a south-facing spot. The thick bed of south-facing moss that surrounds it on the beech roots should not surprise us. Moss grows in abundance close to the ground where moisture levels remain generally high, even in south-facing places.

The technique of trail blazing, marking trees to show others the way is ancient, but the chalk markings on this beech tree were a little disconcerting. Apologies, the picture is out of focus as I was hurrying to catch up with others, but hopefully you can make out the following: arrows showing the way, the words, ‘Tom’ and ‘This Way’ and a picture of a sad, perhaps perplexed or even angry face. Hopefully Tom is less sad now, having spotted these blazes and been reunited with his kin. He will…

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.

President Obama was visibly furious with his British escort team after his secure cavalcade accidentally drove into the tiny Devon village of Clovelly. The armour-plated vehicles were too wide for the narrow cobbled streets and became wedged. Locals of the picturesque, but sleepy fishing village were woken by the sound of police motorbikes and two helicopters overhead. One resident told us, ‘Mr Obama was clearly upset, but we gave him a nice cup of tea and some homemade biscuits and that seemed to settle him.’ Mrs Avril, from the tourist board thought that it was due to the lead driver following his SatNav, ‘One of the policemen seemed very irate, he ripped a gadget off his motorbike and was jumping up and down on it. I told him he should have realised that he was heading the wrong way just by looking at the sun! That upset him even more…

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.

Regular readers may recall how my chilli plants demonstrated an aversion to wind and cold. Yesterday I spent a full and enjoyable day with some of the team from Sire Technology, who were braving the Pathfinder course.

The day consists of an intense morning of indoor training followed by a good leg stretch in the South Downs. Part of the morning is spent going through a few exercises aimed at awakening the senses and raising awareness. I was delighted therefore when, during the afternoon’s practical exercise, Barry from Sire pointed out something that I had walked past without noticing several times. The photo is taken looking northeast and the corn that is being shielded from the sun’s rays by the trees to the left of the picture is fairing a lot worse than that to the right.

On a tangent… Before writing this post I thought that I would try to solve something…

The Natural Navigator’s day often starts with a quick check that the sun is rising roughly where it should be – blog readers will be the first to know if it doesn’t! As this picture shows it is not always a chore and the time that our youngest is getting up each morning certainly helps make sure I’m ready.

This will be the last week this year when the sun rises north of east and its change as it heads south each morning (and evening) is at its fastest at this time of year.

Time and navigation have a cosy relationship, as John Harrison, inventor of the chronometer that cracked the longitude problem in the 18th Century would attest. The sun, earth, moon and planets and stars have at times been seen as cogs in a huge clock.

So many natural phenomena take their orders from these bodies and tide is one of the best known of these. I took this photo of the tide running past a cardinal off Jersey this weekend. The cardinal is an easterly one, signalling that the safer water lay to the east of it. But could it tell us anything else? With two pieces of information, time and tide table, we can discern others such as the speed of the water and its direction. If we had no other references: no sight of land, no chart, no compass, no GPS… that small patch of water could reveal not only…

Trying to be positive when there have only been a brace of sunbeams all August so far, I have been tinkering with the overcast shadow method. The theory being that plenty of light filters through the overcast clouds and that a thin blade can be used to average the source of this light, ie. the sun. It is better than nothing, sometimes, but it is important to be aware that the shadow will be thrown opposite the brightest light and there are no guarantees that this is where the sun is. Uneven cloud or tree cover are just two of the things that can throw it completely.
