The search continues today for a missing backpacker in the wilderness area east of Merced Lake in Yosemite National Park. Ottorina "Trina" Bonaventura, 80, was reported missing on July 30, 2007 when she separated from her group and failed to return to the Vogelsang High Sierra Camp where she was staying.

Over 100 searchers from counties throughout California, the National Park Service, and DNC Parks and Resorts in Yosemite, Inc. are participating in the search effort. Dog teams and helicopters are being used as well.

Ms. Bonaventura is described as being 5' tall with dyed blond hair and brown eyes. She is an experienced hiker, but does have a history of memory loss.

Search managers are asking that anyone who has been in Yosemite's backcountry east of Merced Lake and south of Tuolumne Meadows please contact them EVEN IF THEY DID NOT SEE ANYONE MATCHING HER DESCRIPTION.

The Incident Investigations Unit can be reached at 209/372-0778.
