It appears that my trip was mostly uploaded after all. It does not show up in the list of "My Trips", but the pictures show up in "My Photos." I can access the whole trip via these photos, but can't get to it otherwise. I added it to "My Favorites", but it won't show up there either. The address for the trip is http://www.everytrail.com/view_trip.php?trip_id=454035
I would like to know how I can claim this orphaned trip so that it show up in "My Trips" and can be edited by me. I don't understand how this happened, but I assume the track file got corrupted during the many crashes that occurred while tracking.
I did download the GPX file, geotag my photos and upload everything as a new trip, but this doesn't explain what went wrong with the first one.
