"I sighted South with the Theodolite"

A theodolite ( /θiːˈɒdəlaɪt/) is a precision instrument for measuring angles in the horizontal and vertical planes. Theodolites are mainly used for surveying applications, and have been adapted for specialized purposes in fields like meteorology and rocket launch technology. A modern theodolite consists of a movable telescope mounted within two perpendicular axes — the horizontal or trunnion axis, and the vertical axis. When the telescope is pointed at a target object, the angle of each of these axes can be measured with great precision, typically to seconds of arc.

Closer to home....A familiar sight in Michigan at the Clare Welcome Center. Although the metal sculptures are not Anarctic exploreres the background of the sculptures does have a history.

 The sprawling interpretation of a road construction crew is actually a tribute to highway workers who have lost their lives on the job. The memorial was conceived and paid for by MDOT employees and retirees, and created by artist Carl Floyd using metal salvaged from highway jobs. It was installed in 1994.
