What an unnecessary tragedy. Or rather two unnecessary tragedies. Here is the last image of the missing hiker, if you have not seen it:
https://www.nbclosangeles.com/news/local/friend-haunted-by-last-images-of-missing-hiker-on-mt-baldy/2275557/Looks to me like about 7.5k on the Bear Flats Trail. From about 8k to 9k, that trail is not a hike in the winter, it is a climb. Even with an ice axe and self-arrest training, you can't be sure of a successful self-arrest if you fall on that narrow hogback at about 9k. A very experienced mountaineer, Ali Aminian, fell to his death around there in 2004. And now an SAR person. What was Mokkapati thinking, continuing on his own? While the image is not clear, I don't see trekking poles in his hands or an ice axe on his pack. Not that I would consider it safe to continue alone with them. He is only a few hundred feet below where you would expect to find a witch's brew of hard, slippery snow on steep slopes, plus deep, soft snow in other places.
And it looks suspiciously like the SAR team member lost his life when they surely knew they were no longer searching for a live person.
Mt. Baldy is a serious place in the winter. Even Ellen and Sally, fully equipped, very experienced, and in every way qualified to be on the mountain ran into trouble once, but fortunately had SPOT's and the good sense to use them. The statement that Mokkapati was an 'experienced hiker and knew the area' is fairly meaningless for winter conditions. I don't know how you keep unqualified people off the mountain in the winter, but you would think warning signs at the trailheads and a write-up on winter safety might help.
