It may be that orange markings are trips such as those to Quale Prison in Germany and Pigeon, Utah. Yellow may significant events in general. The teal markings are definitely the GBO and the date seen in the Flashes. Many tags and markings are not precise in their placement. The reason for this is still unknown.
- The markers seem to be Post-it type notes, with the adhesive on the left. Some dates, such as October 10, look like they're actually marking October 9.
