Maria Loida Tice, 60, was last seen on February 13, 2021, while hiking the strenuous Iron Mountain Trail in the Angeles National Forest, California. She joined a group for the hike and was last spotted by other hikers between 11:30 a.m. and 12:15 p.m. as she neared the summit. Her vehicle was later found at the Heaton Flats parking lot, the trailhead, but no other clues were discovered.

An extensive search by multiple rescue teams failed to locate her. Tice is 5 feet 4 inches, about 130 pounds, with shoulder-length brown hair, brown eyes, and wears glasses; she was carrying hiking poles. Her disappearance is classified as lost or injured during the hike. If anyone was on Iron Mountain that day or has information about hikers seen near the summit around midday, please come forward.
