Lightning struck and injured several people who were visiting Mather Point at the South Rim of the Grand Canyon on Monday.
The Grand Canyon Visitors Center said that several people were standing near the rim when the lightning hit. The South Rim Clinic evaluated four people who had non-life-threatening injuries.
Lighting can strike 10 miles across the canyon, according to park rangers. People who visit the Grand Canyon during summer storm months need to be aware that if lightning is followed by thunder less than 30 seconds later, they should seek shelter in a building or vehicle.
Park rangers also advise all visitors to stay away from exposed viewing points during lightning activity. Visitors should also avoid touching any metal railings when lightning is close.
Lightning strikes have caused serious injuries, even fatalities, in the past at the Grand Canyon.
