What is a primary confluence? What about aerial and water confluences?
A confluence is primary if: • It meets the criteria outlined in the Poles Problem section. • It’s on land, or if in a body of water or ice, within sight of land, so that, on a clear day, discernable land features can be recognized. All other confluences are defined as secondary. They will be accepted if visited but are not part of the primary goals of the project. Note that ANY visited confluence, regardless of whether it is primary or secondary, will be added to the site, even if it is not currently indexed in our database. Aerial photos are not considered successful visits though, and will be posted as incomplete visits. They are very useful for planning a ground-based visit, and add to a successful visit.
