Japanese tunnels near Blacks Link (2010-02-15 #3) [????- ]
After the two short tunnels we saw earlier, we didn't expect much from this. But the fact there was a breeze indicated there would be at least one other exit open.
Just after the entrance there's an alcove on the right, then after a short traight the tunnel takes a sharp right. Corners were used to limit the effects of shots / explosions / flamethrowers from the entrance on people further into the tunnel.
On the second corner there's a wider area that could have been suitable for storage or sleeping.
The most unusual feature is where the tunnel drops down and around almost like a spiral staircase.
You'll see one entrance that has been completely blocked with soil from a collapse, and a tunnel that was never completed. I wonder if that blocked entrance is visible from the outside?
When we emerge, we've traveled right under the ridge, and come out quite a lot lower down than where we went in.
