Fitness for DIY Explorers

Wednesday, February 27th, 2008

People usually have so much to do before an expedition that they neglect their fitness. Often if you have good base level of fitness you can use the early part of the trip to get in shape. For those over 35 there is in this more extreme strategy the increased possibility of injury to a tendon or ligament usually. Muscles tone up fast- two weeks can see a return to past glories but bones, ligaments and cartiledge take three months minimum, or at least should be allowed as much.

The best fitness program concentrates on brute strength rather than mere stamina if you have to choose- why? Because injuries usually occur through the sudden overstraining of your body when hefting something heavy.

But then you need stamina too if the expedition requires paddling or walking with packs or walking along river banks for hundreds of miles. The slant of a river bank can over days and weeks lead to a version of shin splints as I discovered in Canada a few years ago having walked 400 km along the north bank of the Peace River in Alberta.

Sledge towers train by towing tractor tires tied to their waists. Canoeists can train in a pool by having a bunjee tied to one end of the canoe with a scale on the pool side - they have to strain against the bunjee cord to make a certain mark. Inventiveness is key in exploration fitness acquisition because of its deadly dull (usually) nature. Climbing walls are great for upper body and fun too. Mountain biking up hills and down dales is as good as running for aerobic – or almost as good.

I have found that running truly is the ‘king of exercise’ as the master Bruce Lee put it. Unfortunately it is bloody boring even in the beautiful wadi digla area where I train in Cairo. My new and exciting solution: take the gps and turn each run into a number fest. I constantly check my speed as I go up hill and down dale. I measure the distance I have gone and have to go. I cross check this with previous speeds and times and pretty soon I’ve run 2 km then 4 then 8. That’s where I’m at right now.

Train in the hills by carrying jerrycans of water in your rucksack- climb the hill with it in and then dump it for the trip down to save your knees. Which are better built through biking and climbing and yoga than the shock impact of pounding down a hill 20kg heavier than your usual weight.

The best way to train is always with a buddy.

This Year’s Challenge

Cross the Sahara on a push bike- December 2008

Fat tire bicycles offer some intriguing possibilities, in fact one suspects a mtb revolution is brewing somewhere- there are big big big snow and desert trips just waiting to be done.

Our contribution is an attempt to cross for the first time by bike the Great Sand Sea of the Egyptian Sahara from the Gilf Kebir to Siwa Oasis. It’s the world’s biggest sand sea.

600 km through the most profoundly arid region on earth bar none.

We will start at the ‘cave of the swimmers’, so named after the 5000 year old rock art paintings of seemingly diving men on the walls of the cave. This was the place featured in the English Patient movie where Kristin Scott Thomas’s character dies- which we hope will provide a suitably upbeat start to the trip…

We then ascend the Aquaba pass, discovered by Count Almasy (the real life English Patient) and used by him to spirit spies into Cairo behind English lines during WW2.

Over the top of the Gilf Kebir, a plateau the size of Switzerland, only with no groundwater at all.

We then go through the Silica Glass area of the great Sand Sea, a mysterious natural glass that was used to make the chest scarab of Tutankhamun. We will skirt the meteorite crater that may have been the cause of the high temperatures needed to make the sand fuse into glass.

It is then up dune corridors between the highest dunes in the Eastern Sahara- over 700 feet high, more than high enough to put the fear of Ra up a cyclist aiming to cross them. Which we will have to do at their end in order to enter subsequent new dune corridors.

We aim to do all of the above on a suitable fat tire bike such as the Surly Pugsley or similar. We will have two Toyota Landcruisers as back up vehicles.

To donate money or goods to aid this trip email the explorer school or phone Richard in the UK. We will also be raising money for charity, principally an orphanage in Luxor.

how to shit in the desert

Monday, February 25th, 2008

If you are able, and have water, use that to polish your dirty bot as the Egyptians do. If you are wedded to paper use a lighter to flame it after use, or bag it and take it away. Leaving paper, as the Cologne University crew have done at their site 60 km SW of Dakhla is simply revolting. Archeologists of all people should know that paper lasts for thousands of years in dry sand- hence the buried MS in the sands at Oxyrhincus. But no, those German eggheads just kept on shitting in the same place week in week out leaving the white paper behind. The shit has gone- eaten by beetles but the paper, denuded of sand by the wind, remains.

Flame the bloody stuff. No one wants to see other peoples shitty paper in the otherwise pristine desert.

If you have to shit on a featureless sand sheet you will find you are invisible except in a very general sense when 1 km from the camp.

Wetwipe the hands to remove the inevitable. Burn or bag the wipes.

Exploring the desert with camels

Sunday, February 17th, 2008

When is a traveller not a traveller? When he, or she, is an explorer. We all love to explore, even on a micro scale like picking over the beach after the tide has come in.

The desert is like one great beach, and in the case of the Sahara it’s the biggest beach on earth, and despite what we may believe, it is not all explored.

We aimed to set up the explorer school to put people who want to explore in touch with the skills they need. As I had just spent the last couple of years exploring the Egyptian Sahara it made sense to start there.

Typically we spend an entire day preparing to leave for a ten day desert journey. It is always very hectic- Bedouin are, on the surface, disorganised. But we have learnt that each trip breeds its own organisation. We start off with all the bags thrown on the camels higgledy piggledy and then over the next hours and throughout the first two days we perfect a system for that journey. Every trip is different and it makes sense to not be too rigid- take weather for example: the packing will be different if we expect sand storms and high temperatures or whether we are stomping through the chill of a January morning.

Despite cold starts, the Sahara in winter is the best time to visit. Sunny and clear by day but never more than 25/26 degrees. By night it can be freezing and if you sleep out without a tent, which is the best way to see the stars move through the night sky, you may wake to find frost on your sleeping bag.

The Bedouin teachers/guides get the fire going before dawn. It is built with any sticks and brushwood we find during the day together with slow burning acacia wood carried in camel bags as a reserve. The trick is to stand the pot downwind actually in the fire so the wind blows the flames around it. No petrol or gas stoves allowed! Bread for breakfast is another skill we learn: scrape away the embers and lay out unleavened dough on the hot sand. Cover with more sand and embers and cook for fifteen minutes. Uncover again and dust it off with a clean paintbrush (or your hand) and you have delicious bread. Surprisingly the sand doesn’t stick to it at all.

Then it’s time to load the camels. This is the main skill we learn from the Bedouin who have practised the art since camels were first brought to Egypt about 500BC. The key is balance. Each load is done with a balancing load on the opposite side of the saddle. A female can take 150Kg, a male over 250kg. Mostly we take females as they are less unpredictable and more friendly. The key knot is very simple- just a stop knot threaded through the weave of the rope held in place by tension. This basic fastening is used in place of complicated straps everywhere on the camel’s saddles. It has the great advantage that if a rope breaks you can repair it easily.

Our journeys take us into the Western Desert around Dakhla oasis, the longest continually inhabited area in the Sahara- there are house remains in Dahkla over 13,000 years old. It has been a trade route centre for as long as there have been trade routes, and it is these old routes that we set out to explore. Curiously it is our exploring, not Bedouin knowledge, that has revealed new information about this remote area. The local Bedouin previously only visited the land to the East, not the West and South West. This was because of banditry in previous centuries closing the old West-East Sahara routes which caused a decay in local knowledge. Those old routes are still marked by ‘alem’ or stone men, literally several flat stones piled on a prominent rock and indicating a route. Often we find the tell tale furrows left behind by very ancient camel routes and always we find stone age tools, pottery, bones and closer to Dakhla even human bones and winding cloths from disturbed graves that date at least from Roman times.

The terrain of the Western Desert is sandy, real desert, with dunes and sand sheets, mirages and dried lakes crusted with salt. But Egypt has the most varied desert terrain of the whole Sahara. In a typical day we will cross a dune barrier, wind our way through buttes and mesas as in Monument Valley, made famous by cowboy films, dip into canyons and file through rocky outcrops. The sheer variety hides old water depots full of broken pots, burial sites and the hidden nesting sites of Saker falcons.

The main part of the day is spent walking and learning new skills such as navigation and desert survival. Bedouin only ride their camels when they are in a hurry, either on a raid or taking them to market, or making a short journey. Walking is the best way to appreciate the desert and to find treasure beneath your feet. But, if you disdain boots, make sure your sandals don’t rub your Achilles tendons as mine did at first- it’s a real killer.

One of the exercises we devised was locating the buried water drop. Camels can go for many days without water in winter (months if there is vegetation to eat) though they do need time to recover. To save the camels we give them a drink after five days. A camel can guzzle fifty litres in five minutes so the water is hidden before we set out. As a test of compass skills (no GPS allowed) we give only the bearing and distance in paces (each person having already measured their pace) and then, like the search for buried treasure, which it is, in a way, the race is on. We haven’t failed to find one yet so increasingly we do this exercise using only the sun as a compass having first learnt how from the Bedouin.

The Bedouin who accompany us are the true teachers of desert exploration. Any time of the day I would ask Ali which way was north. Even without the sun he could tell me within five degrees. At night it is the camels who show the right direction. By some homing instinct they always go to sleep with the bodies pointing towards the starting point of the journey, however many twists and turns we may have made on the way.

One of the great lessons of desert exploration is travelling by night. This is highly dangerous by car but safe by camel, if there is a moon. By lining up the two side stars of the Great Bear and moving a short distance up the sky one always finds the Pole star and so true north. By watching the way stars revolve around the Pole star it is possible to tell the time at night with considerable accuracy.

Our exploration goals are simple: make a map of the journey, record what you find, and be the first at a confluence point. Confluence Points are whole integer intersections of lines of Latitude and Longitude. The first person to record their presence at one wins a place on the extensive Degree Confluence Project website, a kind of Royal Geographical Society for amateur explorers.

Map making is possible because the only accurate maps of this desert are 1:500,000 made in the 1940s. Sat photos, though useful after you’ve been somewhere, are too confusing in place of real maps. We made our first expedition without any map at all, just using a compass and GPS to record bearings and positions on a sheet of graph paper. Over time we have added information to make a detailed record of the area we aim to explore. Each trip, though, we go a new route, very often one which rarely crosses camel or vehicle tracks for days at a time. One set of tracks we were happy to find: the tiny narrow tracks of a baby Ford left by Laszlo Almasy in 1932- he was the real life Hungarian explorer on whom the English Patient was based. His car tracks were preserved in the surface of black gravel lying on sand that he had disturbed but the wind could not erode.

Coming into the oasis after ten days in the desert, the sudden green is like a dream. There are springs where you can dive into clear water and feel your body suck up moisture again. But all too soon the pleasures of the Oasis wear off. As the Egyptian explorer Hassanein Bey wrote: “When the desert smiles there is no place to be but the desert.”
