One German man is dead and another is missing after going hiking during the heat wave that's scorching the Southwest. Stefan Guenster, 57, died after becoming dehydrated while hiking the Ventana Canyon Trail on Sunday, when temperatures hit 115, a record for the date, reports the Arizona Daily Star. Marcus Turowski, 33, is missing. A third member of the party who went to seek help survived. Two other hikers died in the area on the same day, including a 19-year-old woman who called for help after becoming lost and died before rescuers reached the scene. Her male companion was hospitalized.
Heat records for June 20 were set in parts of California and Nevada as well, where other heat-related deaths over the weekend included a 25-year-old Phoenix man overcome by extreme heat while hiking in the Superstition Mountains and a 28-year-old woman who died while mountain biking, reports the AP. The Arizona Republic reports that the search is ongoing for Floyd Roberts, a 52-year-old Florida man who disappeared while hiking in the Grand Canyon on Saturday afternoon.
