A 21-year-old woman died after falling about 300 feet in Colorado's Rocky Mountain National Park over the weekend.

The Severance, Colorado, woman and a 25-year-old man from San Angelo, Texas, fell while climbing in the Flying Dutchman couloir between Longs Peak and Mount Meeker in northern Colorado on Saturday, Rocky Mountain National Park officials said in a news release Sunday.

Park officials said visitors helped the critically injured man as other visitors called park staff for help. Park rangers and paramedics called in a Colorado Air National Guard helicopter to take him to an area hospital.

Park officials tried to recover the woman's body on Sunday, but said they couldn't because of the weather. They said they plan to recover her body on Monday.

The two victims were not named in the release. The woman’s death marks the fourth fatality at the park this year, reported the Fort Collins Coloradoan, part of the USA TODAY Network.

Park officials are still investigating the fall. They said 31 people helped in the rescue.
