Download the Google Earth Plugin
here. Once you have downloaded it*, Open the skatemontana.kml file from within Google Earth and you will have All of the parks in the state plotted. The file is also set up so that you can just hit play below the "places" window, it will fly you through the state zooming in and stopping at each location in Montana.
*Tip: If you click the link and a window pops up with some weird mumbo jumbo right click the link and save the file to your desktop.
