Clicking on one of the boxes on the map below, such as "Murmansk," will take you to the web page that has further information about that geographic feature--in this case on the Murmansk area. When you put your cursor over one of the boxes, you will see that the cursor changes from an "arrow" to a "pointing hand." That means that there is a link there. Good luck and have fun!
