Check this out, mountains where I've ski'd or snowboarded over the last few years... Viewable in Google Maps or if you have Google Earth you can check it out using that by downloading this KML file and opening it up(right click, save as.... IE saves it as an XML file so you may have to rename the file extension to .KML).
I added some YouTube clips to some locations, and some photo's to some others... It's a pretty nice way to document your trips.. The easiest way to create these files is with Google Maps - My Maps feature, which just requires a Google account to use.. The other way is through Google Earth, and even another way to do this is with a GPS device and some software --
I've been working with the Google Map API a lot recently, and you can now also use these files with KML/GeoRSS Overlays
