On the 5th of September I mentioned this old drainage tunnel that we found in the Belfountain area. Well there was one heck of a noise of falling water and in following it we reached an area where water was dropping down from a pipe that went straight up and water seemed to be spraying in through crevices in the wall.
it turns out that this tunnel goes under a small but deep lake along the valley wall and so instead of being underground here, we are underwater.
Just like in caves – falling water generates one heck of a breeze. I crawled up the pipe in front, but turned back at the base of the downfall because it was a little intimidating, very slick and you could hardly see for the wind and water in your eyes – besides, I could not see the point in emerging in the middle of a lake – short of swimming there would be no place to go.
There is probably about 15 – 20 feet of water overhead.
