Things are looking down or, perhaps more appropriately, I'm looking down on things. Western Libya, 1990, and four Birdwagen Mark III's with Failing Y1100 vibrators approach the bottom of the escarpment.
When you stand relatively close to a seismic vibrator you can literally feel the earth shaking. I don't know if you could feel this jebel shaking or not but certainly had we set geophones on it we'd have detected it shaking.
Four in a Row is an expanded view of yesterday's photo (and also the photo I processed in the soon to be released Topaz Clarity.
Today's photo is of a seismic vibrator - a Failing Y1100 on a Birdwagen Mark III hydraulic 4-wheel drive buggy.
On this survey we were using four Failing Y1100 vibrators mounted on International 6x6 trucks as our energy source. In this photo you can see the four vibrators shaking the ground and carving their way through the maize. In the foreground a spare fifth vibrator sits idle, ready to go to work if one of the other four breaks down. In the background are the Schoonspruit/Skoonspruit grain silos.
After Heuningspruit we found ourselves camped near Bultfontein. This was almost certainly taken with my Tamron 500mm mirror lens as my records show the next longest lens I owned at the time was a 300mm.
