Type in a description for the placemark in the Description field, which will be displayed when a user clicks on the placemark. In this example, we typed “Bristlecone Pine Tree”. In the New Placemark dialog box, type in a name for the placemark in the Name field. Move your placemark's location by clicking and dragging its icon, or by typing a latitude and longitude into the New Placemark dialog box. Also, a New Placemark dialog box appears. A placemark is automatically added to Google Earth. Click the Add Placemark button in the toolbar.
