You obliviously know the area and what areas aren’t closed because of the Lake fire that was almost 2 years ago. The fire closure area is to protect the public and environment. The original closure was to fight the fire and to put out hot spots. The area stayed closed because of public hazards of burnt trees falling, rock slides, flash floods, trail damage, etc. It will open again when the Forest Service deems it safe again. For it to be safe for the public the Forest Service is checking new growth status and will be removing dead tree hazards. Then the trails will need to be repaired and cleared for use. It seems like a slow process but that’s nature.
Please get involved by signing up as an SGWA volunteer. Also it helps to contact San Bernardino National Forest Service to stress the importance that San Gorgonio Wilderness is to the people of Southern California.
