Here’s a report from Jill G‘s log. She and a group hiked Cucamonga on 1/16. They wore microspikes to Icehouse Saddle, then switched to crampons. The traverse around Bighorn would be my biggest concern.
She can probably fill you in on the details.
Ultimately, it’s going to depend on weather and snow conditions. If you have fresh snow, you’ll be breaking trail and need to know how to navigate and read conditions. If the snow gets mushy, it can actually be worse because your footing is less sure.
