Ditto to what Ryan & Seventy said: my tracks always line up properly on Google Earth, except for when the GPS is obviously having trouble (occasionally in deep valleys, indoors etc) in which case you can easily spot the errors as the track randomly takes large jumps. Here's my Lynn Peak track for comparison:
You can see the "typical" error in the difference between the lines from a couple of different trips. In 3D, this looks the same as Ryan's plot.
Something definitely looks wrong as your track is shifted to the west - perhaps a coordinate system error but I'm no expert..?
