The search for missing Yosemite hiker George Penca has been scaled down to a small area where the Hawthorne man was last seen.
Penca was reported missing nearly a week ago after he failed to return from a hike to the top of Upper Yosemite Fall. Initial search efforts began Saturday morning with 105 search-and-rescue workers from around the state.
After a week of searching, the strategy was changed because of continued risk of exposure for rescue workers and a lack of clues about Penca's location.
Yosemite National Park is asking anyone who has been in the area of the Upper Yosemite Fall Trail who may have information on George Penca to call the Yosemite Emergency Communication Center at (209) 379-1992.
Penca is 5-foot-10, 240 pounds, and has dark brown hair, blue eyes, a stocky build. He was last seen wearing gray sweatpants with white stripes, a black t-shirt that says "D&B" across the chest, or a black tank top, and gray/blue running shoes.
