A little more perspective
The survey distinguishes architectural height from both the historic measurement and the peak’s elevation above a vertical datum. Different starting points explain why credible sources can give different numbers for the same obelisk.
This record places the architectural base on the scene baseline. Its 169.046-meter height is about 15.4 meters below the Space Needle’s beacon-inclusive height. The illustration represents the stone monument, without surrounding flags or terrain.
