ANZA BORREGO, Calif. -- A 28-year-old hearing-impaired woman was in fair condition Thursday after spending more than three hours lost in Anza Borrego State Park in temperatures exceeding 112 degrees, authorities said.

San Diego resident Alicia Borgongo was hiking near Villager Peak when she became lost in a sandy area and took shelter next to a bush at around 3 p.m. Wednesday, said San Diego County sheriff's Deputy Scott Sterner.

Borgongo used a cell phone to text her mother, but the phone's battery died shortly after 3 p.m., Sterner said.

A sheriff's helicopter and a state parks aircraft were used to search a 12-square-mile area for Borgongo, who was found sometime after 7 p.m. around four miles from the trail on which she had been hiking, Sterner said.

He said that by then temperatures had reached "upwards of 112 degrees," but Borgongo is in fair condition following her ordeal.
