Lightning strikes have killed two in two days at Rocky Mountain National Park, a statement from the National Park Service revealed.

On Saturday, a lightning strike injured four people near Rainbow Curve at 10,829 feet along Trail Ridge Road. Four were transported to Estes Park Medical Center via ambulance. One of the individuals later died from his injuries.

On Friday, a lightning strike injured eight people on the Ute Crossing Trail. The injured hikers suffered a variety of injuries. Rebecca R. Teilhet, who had been hiking with her husband and a friend, died on scene from her injuries. Her husband and friend were transported by ambulance to Estes Park Medical Center.

The other five victims drove themselves to the Estes Park Medical Center.

“No place outside is safe. We are right now, in July, at the peak of the lightning season,” Richard Kithil, who operates the Lightning Safety Institute, told CBS4. “You want to be off the high ground, down into the trees. Or better, near the trail head. Or better than that, in your car around 12 p.m. or 1 p.m. at the latest.”

 According to the National Weather Service, if you are trapped outside with no safe shelter anywhere within close proximity the following actions may lower your risk of being struck or injured by lightning: 1) Leave elevated areas, 2) Never lie flat on the ground, 3) Never shelter under an isolated tree, 4) Never use a cliff or rocky overhang for shelter, 5) Stay away from ponds, lakes and streams, 6) Stay away from objects that conduct electricity.

The National Park Service says that the last lightning fatality that took place in Rocky Mountain National Park was in 2000.
