Long Valley got a good layer of snow prompting the NFS to close the gate on the road that leads to the geologic site and the loop to Owens River Road. You may park at the gate and hike in to fish the canyon. The dirt road leading to the interpretative site is still passable if you have a four wheel drive vehicle. Dry dropper/bead head combos, or swinging streamers and soft hackles with a light sink tip or floating line will get you into fish here if you do not mind the cold air temps.
