The rescues come two days after the Phoenix Parks and Recreation Board voted to launch a test program set to begin on Friday, July 16, that would close Camelback Mountain -- both Cholla and Echo Canyon trailheads -- and the Piestewa Peak trailhead when the National Weather Service issues an Excessive Heat Watch.
