I dug out my 9-year-old Garmin GPS the other day and brought it on a snowmobile ride near Grand Lake, Colorado. It gave me a chance to use the great, free visualization tool GPSVisualizer.com.
You can use this tool with any GPS or GPS-enabled phone.

Here are the results - click for a larger image:

Here is elevation projected on a satellite image. You can see me doing little hill climbs at the highest altitude (in purple), and then jacking around a lot while everyone else did bigger hill climbs (in blue, under the “Gravel Mountain” waypoint).

This is the same elevation coloring, but projected on a topographic map, and showing the entire morning ride.

This image shows the entire morning ride, and is colored based on distance traveled. You can see where we start in the parking lot in red, and where we wind up back at the cars in purple.

GPSVisualizer.com also provides an elevation profile - here’s elevation versus distance traveled.

Finally, this image shows elevation over time. You can see how we fooled around at the top for a long time (in purple), and where we hit the parking lot four separate times (in orange and red).

If you read this far and want to play yourself, but don’t have any GPS data offhand, please help yourself to the GPX files used to make these images:

• GPS GPX file of the whole ride
• GPS GPX file of the top of Gravel Mountain

Cheers.
