JACKSON, Wyo. (AP) — Authorities say a climber has been killed on the Grand Teton in northwestern Wyoming.

Details were sketchy but Grand Teton National Park officials say the woman apparently fell at about 8 a.m. Monday. Her name and hometown weren't immediately released.

The Jackson Hole News & Guide reports the woman was with a guide on the 13,770-foot mountain, the highest in the park and the second-highest in Wyoming.

Park spokeswoman Jackie Skaggs says a second person suffered serious injuries in a separate incident Monday.

Skaggs said that person slid 150 feet down a slope along the Paintbrush-Cascade Canyon hiking loop. The person's name wasn't immediately released, and it was unclear if it was a climbing or hiking accident.

The person was airlifted to a hospital in Twin Falls, Idaho.
