Visitors to backcountry areas of Grand Canyon National Park can now subscribe to a new emergency warning system. The Grand Canyon River Alert System (GCRAS) is s free, subscription-based service specifically designed to send custom hazard-related alerts to satellite messaging devices, the first system of its kind in the nation. Visitors can also subscribe and get the alerts through a cell phone when cellular reception is available. At the core of this new alert system are authoritative geospatial data sets that are developed, maintained and served by USGS' Grand Canyon Monitoring and Research Center.
