PLB Activation Frog Lakes Area. At 2141 hours, the Team was called for a personal locator beacon (PLB) activation at Frog Lakes. There was no communication from the PLB owner or his party of three males over 70, and the nature of the request was unknown. The party’s emergency contact was connected with a Mono County Sheriff’s Office Deputy/SAR Coordinator and she relayed that each of the three had various cardiac histories, some serious in nature.

Rescue base was established at Big Valley Lake, aka Big Virginia Lake. The ops leader deployed a hasty team of two with medical equipment including a first-out bag, airway support including bottled oxygen, and an AED. Team 2 was deployed shortly after with additional medical equipment, including a hypothermia management and prevention kit (HPMK) and hot packs.

Team 1 quickly reached the subjects at Frog Lakes, approximately 1.6 miles from the trailhead. Upon inquiry about the activation, the party stated that all were in good health and that their PLB may have been malfunctioning. Team 1 confirmed that the device was no longer transmitting an active SOS, and all personnel returned to base. The call terminated at 0025 hours August 28.
