My colleague Ken using a Tellurometer for survey work on Mt Lacey, in the Prince Charles Mountains. Obsolete now due to satellites and GPS, back in 1966 the Tellurometers were the best way to measure distance between two points. With two on separate mountains firing a microwave beam to each other, it was possible to measure distances to within a few centimeters. When this was taken, we were in contact with a surveying field party further to the south. Temperatures were about -12 C at this stage.

An updated copy from an old 1966 slide. I was assisting with the surveying from this peak (mainly lugging equipment uphill). Here looking down on our tractors, caravans, and the tracks they left as we arrived (view large and they are easier to find). The "cloud" effect is from light on sastrugi (ridged snow), the blurred black foreground was from the rocks close to me. This was our first major camp on the field trip and, having climbed the steepest part of the rise onto the plateau, we depoted one of the bulldozers here, continuing with just two.

From an old slide. On Mt Lacey in the Prince Charles Mountains we erected a trig point and took readings of distance and bearings to a field party travelling to other peaks in the area (the machine is a Tellurometer for measuring distance very accurately - something like half a radar set, one was required at each end of the link). The distant mountain range is about 30km away.
