Makes you wonder. Which one is right? 10047 or 10064. Garmins are real nice.

When I used to fly KC-135's, we used to do emergency approaches to airfields using Handheld GPS's and they were very accurate. Your's is probably closer to the real summit altitude.

GPS

Civilian GPS units usually have a very small factor of error , this is usually only a few meters in Lat, long and elevation.the one in pic is within this "few meter" range.My magellan does same thing,it will even give a different elevation for same peak on different days...not by much though!
I would trust the national geodetic survey's reading of 10,064'.If they can determine that Everest grows about 1/4" a year, I think they can tell within a few inches for Baldy.
Also, the Garmin website says that the elevation accuracy may be off by as much as +/- 400' depending on positions of satelites at time of reading.....wow!

True elevations

Who knows for sure the true elevations? It is interesting, though, that the latest elevation for Mt. Whitney is 14,505 ft.--making it the only peak in the lower '48 over 14,500 ft. Almost more note-worthy is Mt. Williamson's new elevation listing--14,403 feet; a gain of over 28 feet! Do you suppose Mt. Barnard is over 14,000 feet again?
