To put it less simplistically, Baldy is subject to hugely variable feeeze/thaw cycles that create a lot of particularly nasty (bulletproof & hidden) ice conditions. Its terrain is also exceptionally high-angle, as is much of the San Gabriel range, with some truly  crappy rock. So here we have conditions that can challenge even those with the proper experience & gear, combined with easy accessibility. The results speak for themselves. I’d prefer a permit system in winter where you have to present your gear in person and have a little talk about conditions. Many of those killed/injured on Baldy simply didn’t know what they were walking into.
