Although this looks at first glance to be an aerial shot, I'm actually standing on the on terra firma for this shot of our vibs approaching 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.
The last two day's I've posted photos looking down on a bulldozer cutting a trail down an escarpment in western Libya. Today's photo is of surveying the escarpment looking up from the bottom.
After the surveyor cut his line, a 'bridging crew' would follow along behind and cut smaller trees to form a walkway, or bridge. Typically three poles wide and nailed together, it made walking the lines considerably easier for the rest of us and in most cases kept our feet dry also. It also meant that relatively few people were actually tromping across the jungle floor.
This photo, looking to the west from the eastern end of the survey area shows the grid of lines we left across this area. When you look at the Google Earth satellite view you can't see any tracks so no lasting damage, apparently. Also, no new mine shaft so it looks as though our client didn't find what they were looking for.
