The natural Navigation: The Right Course, Naturally

… or a clue to direction. One of the challenges in natural navigation that never goes away is the need to constantly change our focus. Our eyes have a tendency to drift towards a middle-distance focus. This can mean that clues in the background and the foreground can be easily overlooked. The first photo of a field on the lower slopes of a volcano in La Palma is a good example of this. There is a temptation to look to the trees for help, and they do offer some, but better help can be found much closer as the second picture shows. The southern side of these flowers is opening up before any other side. When seen close up like this it is hard to miss, but we all walk past clues like this everyday and our eyes are so often drawn elsewhere.

I was at the Royal Geographical Society for the Travellers’ Tales Festival yesterday, to give a talk about my book. Less than a fortnight until it hits the shops!

I arrived early to listen to some of the other speakers, including the National Geographic photographer, Frans Lanting. The speakers’ notes are very explicit about not running over your alotted time, but Frans was on a serious roll. That guy is not short of slides. It was enjoyable but as it shot past it’s slot, and then on some, enjoyable though it was I had to nip out. I’d inspected the schedule for the day and had a plan of sorts; listen to this talk, pop out for a bit to meet a friend, return for my talk at 3.30 etc.

In the nicest possible way it all went wrong. Outrageous name-dropping time…

In the speakers’ waiting room (called…

I landed back at Gatwick last night following an accidental visit to Tenerife.

The wind has been my friend on so many occasions recently, a dependable breeze helping me on my way through the woods or the clouds scudding overhead pointing the way home. It was probably time that it reminded me that it is not just in the business of helping me on my walks.

The plan was simple: I wanted to use a one week gap in the diary to get out to one of the wildest spots within five hours of home to do some natural navigation research. Days one to six went well as I walked, mainly without reference to map, compass or GPS (all were within reach), around the dramatic volcanic landscapes of La Palma in the Canary Islands. More details to follow here over the coming weeks, including photos of the incredible ‘

‘Courting bustards’ is not an excellent new profanity, something that would sound good with rasping voice and sent in the general direction of a parking warden putting a ticket on your car, it is actually a reference to the romantic habits of the male great bustard bird.

Researchers from the IE University School of Biology in Santa Cruz, Spain, have found that the male bustards align themselves with the sun when trying to attract a female. Their white feathers, the bustard’s equivalent of an Armani suit/Ferrari/pair of Reeboks – delete as applicable, show up better when aligned to catch the sun’s rays. Dr Tommaso Pizzari, an ornithologist from Oxford University, observed that although it made the birds more vulnerable to predators, it certainly made them more visible to females. ‘That’s why we think these puzzling traits evolved and are specific to males.’

Although the bustards have been found to do…

After an enjoyable private course on Friday – we finished standing in a field looking at Orion, the Plough, Cassiopeia and, of course, Polaris – it was time for a family outing to West Wittering beach early on Saturday.

I adore the Witterings in winter, the barbecue and beach towels may have to stay at home but it is invigorating to get blown along on miles of abandoned sand. In between games of hide and seek amongst the beach huts, games of football on the sticky sand and races to pieces of seaweed, I noticed some interesting patterns in the sand.

This photo shows how there tend to be broad ripples parallel to the coastline itself, but closer inspection reveals more subtle patterns and these can be used to decipher the action of the water and therefore yield more clues to direction. The ripples of sand fan out over…

I went for a walk in the South Downs yesterday afternoon. The air was cold, there were still chunks of ice lining the north-facing side of chalk ruts in the path. The sun was up for the first part of the walk and made direction-finding easy. When it fell below the hills to my southwest it gave different opportunities. One of my favourite dusk techniques is to use the light reflections of cloud edges to gauge where the sun must be behind higher ground. This photograph from 4.30pm yesterday shows this effect quite clearly. The sun is reaching the far ground, trees and clouds, but it does not light the clouds equally. The bright edges act almost as a parabola, pointing the way back to a now invisible sun.

The picture was taken looking northeast. The very perceptive will have noticed that there are molehills in the foreground and that…
