Emergency markers on the trails

In development for over four years and guided throughout by input from first response and geospatial experts who participated in national, state and local focus groups, USNG Emergency Location Markers (ELM’s) offer a way for communities to mark locations such trail intersections, camp sites, buildings, boat landings, and other response locations with a marker that works with GPS, is location specific, unique across jurisdictions, and is nationally consistent.
