Well, since you started the thread...
I am trying to figure out how they changed the official elevation of Mt Whitney, and if I ever get the explanation straight, I'll post a little writeup.
It has to do with where the zero-elevation point is (now it is someplace in Canada near the St. Lawrence river). And also with tying multiple elevation survey grids together.
But I haven't got my questions answered yet, and every time I ask one or two, the answers cause more.
Does anyone here have a handle on the elevation changes?
