A missing snowboarder was found alive Tuesday near Alpine Meadows ski resort. Sean Hackett of Ithaca, N.Y., was found less than two hours after his brother, Brian, reported him missing, according to a report from the Placer County Sheriff's Office. The two were on the backside of Alpine Bowl around noon when Brian lost sight of his brother during a backcountry wilderness excursion. Brian returned to the resort and reported Sean missing at about 3:30 p.m. Placer County Sheriff's Tahoe Nordic Team searchers along with the sheriff's helicopter Falcon 30 crew started their search a half hour later. An hour later they found Sean's tracks, and found Sean about 3.5 miles from the resort in area known as Willow Creek near Diamond crossing, according to the report. Sean was airlifted. He did not require medical treatment. According to the report, Sean is an active outdoorsman and thought he could snowboard around the mountain to the Sherwood lift. He got lost when he misread his ski trail map, the report stated. Backcountry outside of ski area boundaries is not patrolled and sometimes subject to dangerous condition such as avalanches, the report said. Hackett was not charged with skiing outside of a boundary or in a closed area, according to Dena Erwin, sheriff's office spokeswoman.
