Two Women Killed in Fall at Grand Teton National Park

— -- Two women were killed in a fall while trying to climb the Teewinot Mountain in the Grand Teton National Park in Wyoming, officials said.

Tyler Strandberg, 27, originally from Raleigh, North Carolina, and Catherine Nix, 28, originally from Port Chester, New York, both died after falling about 200 feet on Saturday, the National Park Service said today.

The women, who both lived in Jackson, Wyoming, were pronounced dead on the scene, the park said.

Standberg and Nix were climbing with another woman, 26-year-old Rebecca Anderson, who called 911 to report the fall. Anderson said after the two women fell out of sight, she tried to yell down to them, but heard no response. Anderson was not injured, the park said.

The three women were trying to climb the East Face of Teewinot Mountain, which the park said is the "typical" and "easiest" route to the summit of Teewinot.

The women were not using ropes at the time, the park said, and were apparently looking for the correct route.

"Though the route is frequently climbed without ropes, the terrain is very steep and good route-finding skills, mountaineering experience, and caution are essential. The climbers were well off the East Face route and in much more difficult technical terrain when the fall occurred," the park said in a statement.

A spokeswoman for the Grand Teton National Park did not immediately return ABC News' request for comment.
