A Small Depression - N - (-------------------------------------------------) - <---(M)---> - - - - This section of the tunnel seems to be the place where the lava that flowed through at one point finally cooled off. Instead of continuing to melt through the surrounding rock, the liquid-hot magma settled into one place, spreading out and leaving the ground level in this area slightly lower than the rest of the tunnel.
