• Call 911. If you have poor cell reception, ride or hike to higher ground. Note that cell reception varies across the CAMBA system, and is non-existent on some trails.
  • Tell the dispatcher the nature and severity of your emergency. Use the nearest Emergency Location Marker to provide the U.S. National Grid (USNG) coordinates that identify your location (the two rows of four large numerals describe your location. If requested by the dispatcher, also read the small numbers and letters at the top of the Emergency Location Marker).
  • You may also determine the USNG coordinates for your location using the USNG app, which you should install on your phone in advance of your ride. It functions without cell coverage and it is free.
  • If you are not at an intersection with an Emergency Location Marker and unable to use the USNG app on your phone, you may need to ride or walk ahead or back to locate the nearest marker. Markers are located at 1/2 mile intervals or more frequently.
  • Dispatchers will transmit your location to multiple agencies and responders. Responders will use your USNG coordinates to locate your position.
  • Be patient. It may take some time for responders to reach you. In many cases, they will need to travel the same trails as you did to get to your location.
