Holy Jim wouldn't be a mudslide problem in dry weather. (Landslide if it burns, I guess.) It could conceivably have a conditional closure, like Maple Springs Road.
The road in might be, from mudslided in burned trabuco canyon flowing past the confluence. But maybe the road would be open just up to HJ parking lot, or open to bikes even if closed to vehicles. or just closed during rain.
