Well, this is some sad news.

An unidentified woman was sent to the hospital today with life-threatening injuries after part of a redwood tree fell and smashed her at Stern Grove today. It seems, according to KCBS, that the woman had just walked her dog, who was not hurt, and as she was getting into her Subaru Outback near Concert Meadow, "part of a tree broke off and fell," crushing her as it came plummeting down.

The woman was whisked away to San Francisco General Hospital by paramedics, in critical condition.

Update: She died at 12:14 p.m.
