Authorities said the body of Steven Grunwald, 24, was found in the Notch below McHenrys and Powell Peaks in the Colorado park. Grunwald, from Greenville, New York, last had contact with his family and friends on Aug. 28, and was last seen that day in Boulder, according to a news release from the park. A friend reported him missing on Sept. 10. His exact route remains unknown, but authorities believe he may have been trying to hike the Glacier Gorge Traverse on Aug. 29. The route is considered “difficult” terrain, and includes 11 peak summits over approximately 19 miles. Grunwald’s vehicle was found parked at the Glacier Gorge Trailhead on Sept. 10, and search efforts began the next day, the release said. Recovery operations — which included a helicopter and a team of rescue dogs — were made difficult by poor conditions, including snow, strong winds and windchills of 11 degrees on Saturday, according to the park.

The manner of death was deemed accidental, according to a statement. Prior to the discovery of the body, friend Rocco Cavalluzzi told the Fort Collins Coloradoan that Grunwald was skilled in the outdoors. “It’s a scary situation, but I absolutely feel like he could still be alive because if anyone could survive it is Steven,” he said. Cavalluzzi also said that Grunwald was thinking about moving to Boulder.
