Ohio university professor dies after falling 150 feet from mountain peak in Alaska

A 52-year-old university professor from Ohio died after he fell off the peak of a mountain in America's largest national park. David Shrider fell 150 feet Friday down the slope of Donoho Peak in Wrangell-St. Elias National Park and Preserve in Alaska, the park said in a news release Saturday.

Just before the fall, "a family member in the hiking group reported that he asked for help and then rolled approximately 150 feet down a slope. When a member of the group found him, he was dead. His son, who was a member of the party, called 911," the park said. Wrangell-St. Elias National Park and Preserve Search and Rescue team members and an Alaska State Trooper used a helicopter to get the hiker's body Saturday afternoon, the park said.
