SURVEYING FROM A MOUNTAIN TOP 



In making a geodetic survey, absolutely flat country is a much greater obstacle to the 

 surveyor than a range of mountains. Indeed, a high mountain, commanding extensive views 

 in all directions, is often a godsend, as it may serve as the apex for triangles drawn in all 

 directions. Here is such a mountain, Uncompahgre Peak, on the summit of which, 14,289 

 feet above the sea, a triangulation station was erected when surveying the Colorado arc 

 (see page 665).
