Reply to "Elevations from various sources"

The problem with deferring to Google Earth is that those elevations seem to be based on surveys done in the past, whether the late-1800s, the national 1927 survey, or something in the 1950s. The reason I say this is, I mapped a course that went across a dam. Google Earth showed the original contour in the Elevation Profile. It is a flat road, but the profile shows a high point of 5656', and a low point of 5590'. Not accurate.

But, I would say that if one used GE for elevations in close proximity to one another, and there had not been lots of dirt moved to create the grade (how would one really know that for sure?), then the elevations would likely be relative to one another, whether precise, or not.
