• The CAMBA trail system employs two different types of location references: CAMBA Location Markers and Emergency Location Markers.
• Each major CAMBA trail intersection has a CAMBA You Are Here map, plus a CAMBA Location Marker with a Letter/Number reference, such as N9, which you will also find on the map. Minor trail intersections just have CAMBA Location Markers on a post.
•  Use the CAMBA Location Markers as checkpoints on your ride. If you are unsure of your location, check the numbered CAMBA Location Marker at the next major intersection and find that location number on the You Are Here map.

• All intersections also have an Emergency Location Marker labeled with U.S. National Grid (USNG) coordinates used for emergency services, expressed in two rows of four numerals.
