Alice Yu Xie

The National Park Service released the above photos of "Alice" Yu Xie, 41, who has been missing since last Thursday after going for a hike on Upper Yosemite Fall Trail. She was carrying a small green backpack pictured on the left.

Authorities in Yosemite National Park are looking for a woman in her 40s believed to be last seen on Thursday or Friday walking to the Upper Yosemite Fall overlook.

“Alice” Yu Xie is identified by the National Park Service as a 41-year-old Asian woman, a Chinese national living in the United States, who came to Yosemite on a Yosemite Area Regional Transportation System bus from Mariposa on Thursday.

She is described as being under 5 feet tall, weighing less than 100 pounds, with neck-length black hair. She was carrying a small green backpack, pictured in a photo released by the National Park Service. A description of her clothing was not available.

The Upper Yosemite Fall trail Xie was on is described as a 7.2-mile roundtrip walk with 2,700 feet elevation gain. It’s a strenuous walk, according to the National Park Service, which can take six to eight hours or more to complete. The trailhead is near Camp 4 on the floor of Yosemite Valley.

Xie was believed to be on a day hike, with no intention of spending the night out. Yosemite National Park is currently open 8 a.m. to 5 p.m. daily with no camping allowed, due to the COVID-19 pandemic and the regional stay home order for the 12-county San Joaquin Valley region, which includes Yosemite National Park.

Public information staff with the park posted to social media about Xie and her missing status just after 9 a.m. Saturday. The post received more than 700 comments and 2.6 thousand shares by Monday morning.

A social media user identified as Barbara Cone, of Mariposa, commented Sunday afternoon, “My roommate saw her on the trail and notified the park service of where and what time. We sure hope it helps locate her. She was going up as most were coming down in the later afternoon.”

Yosemite National Park public information staff urged anyone who was on the Upper Yosemite Fall trail, walking to the top of Upper Yosemite Fall on Thursday or Friday, to call (209) 372-0216 during business hours, or the Yosemite Emergency Communications Center (209) 379-1992 after hours, “even if you did not see this individual.”
