Map Symbol Legend for Country and Region maps
The combination of a confluence's type(Primary vs Secondary) and visit status can be determined by the shape, size, and nature of the confluence symbol, without referring to the symbol's color.
Depending on the overall size of the map, the size of the set of map symbols varies. The size referred to below is in comparison with other symbols in the same set.

Primary confluences - square
Secondary confluences - triangle
Successfully Visited confluences - a "full sized" solid red symbol
Incomplete Visit confluences - a "full sized" 'hollow' blue symbol(white interior)
Unvisited confluences - a "small" solid grey symbol
Unindexed confluences - any intersection of latitude and longitude lines would indicate a potential confluence, but those without a map symbol do not belong to the current Country/Region.

Map Symbol set examples: These show, from left to right, Primary Unvisited, Primary Incomplete, Primary Visited, Secondary Unvisited, Secondary Incomplete, Secondary Visited.

Confluence Page - maps: MapQuest
This link is available for all confluences.
MapQuest links to a MapQuest page, showing a 'street map', with the confluence marked by a star.

Confluence Page - maps: Multimap
This link is available for all confluences.
Multimap links to a Multimap page, showing a 'street map', with the confluence marked by a circle.

Confluence Page, USA confluences - maps: topo
This link is available for all USA confluences, except for Puerto Rico.
topo links to a TopoZone page showing a topographic map of the confluence location.

Confluence Page, Canadian confluences - maps: topo topo250
These links are available for all Canadian confluences.
topo and topo250 link to a Toporama page. The topo link takes you to a portion of the corresponding 1:50,000 topographic map sheet, and the confluence should be in the top left corner. The topo250 link takes you to a portion of the 1:250,000 topographic map sheet that contains the confluence.

Not all Canadian confluences have a map image available at 1:50,000.

Some confluences will not work because the latitude/longitude of the confluence, which is used to link to Toporama, is assumed by Toporama to be on the top of the map sheet, which, for example, is not the case for confluences that are along the 49th parallel border with the USA.

Confluence Page - maps: aerial
This link is available for all USA confluences, except for Alaska.
aerial links to a TerraServer page with an aerial photo of the confluence location.

Confluence Page - maps: world
This link is available for all confluences.
world links to a Pima County World Map page showing the confluence. The information displayed on the map is dependant on where in the world the confluence is located.

In order to view and use the map, you need the free AutoDesk MapGuide browser plug-in.

Confluence Page - maps: confnav
This link is available for all confluences.
confnav links to our Worldwide Confluence Navigator page. The confluence is shown on a map along with other confluences in the area, as well as showing the confluence location on a world map, and there are multiple ways to navigate, or display, other confluences.
