RAPID CITY, S.D. (AP) — Law enforcement authorities in western South Dakota say an Illinois man was seriously injured after falling 150 feet near Sheep Mountain Table at the Badlands National Park.

The Pennington County sheriff's office says the 26-year-old man was transported from the park to a Rapid City hospital Saturday afternoon in a helicopter from the South Dakota National Guard.

Authorities say the incident happened around 2:00 PM Saturday. The sheriff's office did not immediately identify the man. His condition is unknown.

The Pennington County sheriff's office responded to the scene after receiving a request for assistance from Oglala Sioux tribal law enforcement officers.

Several other agencies assisted in the man's rescue including Pennington County Search and Rescue, Badlands National Park Rangers and Rapid Valley Volunteer Fire Department.
