SALT LAKE TRIBUNE, UTAH – Four people were found dead and three others were missing Tuesday in Zion National Park, one day after the group went into Keyhole Canyon as flash flood struck southwestern Utah. The group of four men and three women from California and Nevada picked up their permit to go through the canyon about 7:30 a.m. on Monday, despite rangers’ warnings that the flash flood danger was “probable” said park spokeswoman Aly Baltrus. Some members of the group took a basic canyoneering course Monday morning before the group made its way into Keyhole Canyon — one of Zion’s shorter technical canyons, Baltrus said. The route typically takes canyoneers about two hours, though advanced canyoneers have been known to complete the canyon in just 30 minutes, Baltrus said.
