National Park Service personnel and others are searching for 73-year-old Kenneth Stensby, of Edina, who did not return from a day hike in Yosemite National Park on Sunday, KARE 11 reports.
The avid hiker left a note early Sunday morning for staff at the Ahwahnee Hotel where he was staying that he would be back from the hike at about noon. He had noted that he was headed to the top of Vernal Fall.
Stensby's dark-colored North Face pack was found at the railing at the top of the Vernal Fall, but he was nowhere to be found, the Fresno Bee reported.
Park rangers were searching along a stretch of hike known as the Mist Trail corridor. About 30 people helped search Monday. A dog team was assisting.
Other park visitors were being asked to check their photos to see if any images were captured of Stensby.
The three-mile round-trip hike to Vernall Fall is one of the Yosemite's most popular, the Modesto Bee reported. The waterfall was the site of tragedy in July 2011, when three hikers died after going over the 317-foot waterfall, the newspaper notes.
