ROCKY MOUNTAIN NATIONAL PARK – The person who died Saturday from a lightning strike in Rocky Mountain National Park was identified as a 52-year-old man.

Gregory Cardwell, from Scottsbluff, Nebraska was the second person to have been killed in two days in separate lightning strikes at Rocky Mountain National Park, RMNP spokesperson Kyle Patterson confirms.

Cardwell's mother says he leaves behind a 22-year-old son, 17-year-old daughter, and his wife. She says Cardwell and his wife planned to spend the weekend in the park along with several other people.

The lightning strike near the Rainbow Curve on Trail Ridge Road affected 13 people Saturday. They were taken to the Estes Park Medical Center. Doctors say rangers and first responders administered CPR on Cardwell, who was directly hit by the bolt of lightning. He was pronounced dead when he arrived at the center.

The strike happened at around 3:30 p.m.

This comes just over 24 hours after a woman died from a lightning strike on the Ute Crossing Trail – which is located on Trail Ridge Road between the Rainbow Curve and Forest Canyon Overlook.

Seven other people were injured. The woman who died has been identified as Rebecca Teilhet of Yellow Springs, Ohio. She had been hiking with her husband and a friend.

In total, 21 people were taken to the hospital -- and two died from their injuries -- because of lightning strikes on Friday and Saturday, an official with the Estes Park Medical Center told 9NEWS.

The last lightning fatality in Rocky Mountain National Park happened in 2000, when a technical climber was struck on the Diamond on Longs Peak.

Park officials are reminding visitors of the dangers associated with being above tree line -- or more than 10,000 feet. That area is very exposed and there are few places to take cover.

Park rangers say visitors should head to lower ground by 12 p.m. to avoid being caught in a dangerous storm.
