Using the legend; turn icons on and off
click the checkboxes to turn icons on and off
You may click the LEGEND button at the top right to expand and collapse the legend for the annotated markers on the map.
Additionally, you may click the icons within the legend to turn "on" and turn "off" those groups of icons in the map.
Click All On to turn all the markers on.
Click All Off to turn all the markers off and see nothing but the original artwork.
Note: Even if you have All On clicked, you may not be able to see all the markers. All markers are only visible when fully zoomed in. If you would like to see each marker, start at the beginning marker (the window that opens when the map loads) and click Next until you no longer have the option. This will open all the markers in turn, and automatically zoom in to the appropriate level.
If you do not wish to start at the first marker, but still wish to pursue a sequenced narrative, click All On, then find the icon you wish to start with. You will be able to click Next to step through the story as if you had started on the first.
