I am rather passionate (some might say “obsessed”) about visiting latitude-longitude line intersections, named “Confluence Points.”  In fact, I have visited nearly 400 of them over 15 years.  See these points and my map here.

My article about this project in The American Surveyor, entitled “Pointed Journeys.”

You can use this project to teach physical and cultural geography, mathematics, biology, environmental studies, geomorphology, and other subjects, using these ideas I list here: Teaching and Learning with the Degree Confluence Project
