RedactedNarrative: On the 8th of August, 2021 I responded to the east shoreline of the main channel of Lake Powell, near buoy 3C, where a pontoon boat had run aground.  NPS Rangers were on-scene and had already conducted an OUI investigation of the operator of the vessel.  I interviewed him and was told the following:  He told me he had been operating the boat while coming from Antelope Point towards Wahweap.  He had previously gotten “turned about” while using a map to navigate and was, consequently, trying to navigate back to Wahweap using his phone.  He said he was traveling about 25 mph, headed in a generally southbound direction.  He was looking down at his phone, which was in his hand.  When he looked up, his course had curved to-port and he was just about to and then did run up onto the rock shoreline.  He admitted to having consumed 6 beers in 7 hours but passed SFSTs administered by the Rangers
  
  Both passengers in the front of the boat saw it heading for the shoreline but did not speak up and warn him in time to avoid the incident.
