The photo below is part of our ‘Front Crew' waiting for another load of geophones, cables and boxes to be delivered.
Sprawled out on the sand, it's like a cold day at the beach, except the ocean is nowhere to be found. I say cold because it does get relatively cold in the winter in Libya.
in the desert in winter, night-time lows below freezing are relatively common – occasionally even cold enough to gel the diesel in the tanks of our trucks!
While average daily highs in January are posted at around 70°F / 21°C, if a cold wind was blowing in from the north it could stay much colder all day. When I first pitched up in Libya in December 1984 I was completely unprepared for the cold of the desert, having been briefed by someone who spent all their time on the coast.
The pole is a piece of angle iron that marks the intersection of two survey lines. You can see the pegs and Land Rover tracks from the survey crews stretching out into the distance. The other line is crossing left-to-right.
The angle iron was called a ‘permanent marker' but in these constantly shifting sands, if it's even still visible, it's unlikely to be here any more.
The front crew laid the geophones. When they ran out they'd catch a break till the next truck load arrived. In the winter they'd lie out in the sun but in the summer they'd huddle in the shade of the trucks whenever they could. Rather than have them lay under the trucks, we made awnings to fit from the truck sides to increase the shade area.
