A Garmin GPS III Plus tags along with me on many of my trips. Once the trip is over I transfer the track log to the PC via WayPoint+. DeLorme's StreetAtlas v5 is then employed to overlay the track onto a map.
The downloadable track files (zip files) contain text data files which may be opened in WayPoint+, StreetAtlas v5 maps maps and GIF pictures (that you see below). If you have WayPoint+ or StreetAtlas you can open the data files and have a zoomable track to view.
For pictures on how the GPS is setup for snowmobiling use - here it is.
Note: The track logs listed here are
short, day trips - often
where no camera has been along. If a camera had been used a
trip web page with track log information is created.
