Degree Confluences

A degree confluence is the exact spot where an integer degree of latitude and an integer degree of longitude meet.

Those spots are not marked in any way on the surface of the earth and generally there will be nothing special to see.
But in recent years, with the increasing popularity of GPS devices, a new sport/hobby has developed: to visit the degree confluences of the earth and publish a report about it on the Internet.
The originator of this undertaking has been Alex Jarrett and the results can be found on the Degree Confluence Project website.
 

There are 179 Parallells between South and North Pole. Each Parallel has 360 degree confluences. The poles themselves are confluences, so the total number of confluences is 64442.
Because the oceans form a large part of the earth, many confluence points are located on the sea. When we restrict ourselves to confluence points which are on solid ground or from where at least land can be seen, the total number of confluence points amounts to about 24000.

To find the container you need go 557 meters in 6° from the confluence point.
